Calculate angle using tanθ = h/l
Slope of velocity vs time graph (m/s2)
Slope of acceleration vs time graph (m/s2)
Percentage error between slopes
Conclusion
From the results obtained, it can be concluded that:
1. The acceleration of the cart down the inclined track is constant as shown by the linear
acceleration-time graph.
2. The acceleration increases as the angle of inclined track increases. This is because the
component of gravitational acceleration parallel to the plane, gsinθ increases with
increasing angle θ.
3. The percentage error between the slopes of velocity-time and acceleration-time graphs is
small, within experimental error
This document is a report on an experiment conducted using a data logger to investigate how the acceleration and velocity of an object moving down an inclined plane is affected by the angle of inclination. The experiment measured the acceleration and velocity of a cart moving down inclined planes of different angles. The results showed that acceleration and velocity increased with increasing angle of inclination due to the larger component of gravitational force acting parallel to the plane. Common applications of this concept, such as cycling downhill or moving goods up and down ramps, were also discussed. The data logger allowed accurate, real-time collection and analysis of position, velocity and acceleration data without extensive calculations.
The document provides details about using data logging to investigate how the acceleration of an object moving down an inclined plane is affected by the angle of the plane. It describes an experiment where a cart was released down inclined tracks of varying angles, and a motion sensor was used to collect data on the cart's position, velocity, and acceleration over time. The results showed that acceleration increased with greater angles, due to the larger parallel component of the gravitational force acting on the cart. Data logging allowed accurate, real-time measurement and direct analysis of graphs to determine relationships. It enhanced science lessons by making experiments quick and engaging for students.

The document summarizes a study that investigated how visual feedback affects human gait and walking speed. Researchers had subjects walk on a treadmill while receiving real-time visual feedback about step length and timing. The feedback took the form of vertical bars representing step length and scrolling horizontal bars that subjects were encouraged to step on. During trials, the speed and spacing of the horizontal bars was altered without the subjects' knowledge. The results showed subjects adjusted their walking speed in response to the visual feedback distortions, demonstrating visual feedback's potential for modulating gait speed during rehabilitation training.
The document discusses using technology and data tracking to monitor personal health and fitness metrics. It provides examples of devices like Fitbit, BodyMedia, and Nike Fuelbands that track metrics like heart rate, activity, sleep, and GPS location. The document also outlines how to use the tracked data with apps and websites to analyze trends and map activity over time to specific locations to improve health and fitness goals.
Phoebe - A Framework of Estimating Fetus Weight and AgeLoc Nguyen
Fetal age and weight estimation plays the important role in pregnant treatments. There are many estimate formulas created by the combination of statistics and obstetrics. However, such formulas give optimal estimation if and only if they are applied into specified community or ethnic group with characteristics of such ethnic group. This research proposes a framework that supports scientists to discover and create new formulas more appropriate to community or region where scientists do their research. The discovery algorithm used inside the framework is the core of the architecture of framework. This algorithm is based on heuristic assumptions, which aims to produce good estimate formula as fast as possible. Moreover, the framework gives facilities to scientists for exploiting useful information under pregnant statistical data.

This document discusses the use of computer simulations in education. It provides examples of how simulations can be used to model predator-prey relationships and increase student motivation. Simulations allow students to explore concepts and see the effects of changes. They also guide learning and reflection. While simulations have advantages like interactivity, some disadvantages are a lack of emotional awareness and inability to adapt to different students. Overall, computer simulations are seen as a useful tool to help teach difficult concepts when used alongside teacher guidance.

Picket Fence Free Fall
We say an object is in free fall when the only force acting on it is the earth’s gravitational force.
No other forces can be acting; in particular, air resistance must be either absent or so small as to
be ignored. When the object in free fall is near the surface of the earth, the gravitational force on
it is nearly constant. As a result, an object in free fall accelerates downward at a constant rate.
This acceleration is usually represented with the symbol g.
Physics students measure the acceleration due to gravity using a wide variety of timing methods.
In this experiment, you will have the advantage of using a very precise timer connected to the
calculator and a Photogate. The Photogate has a beam of infrared light that travels from one side
to the other. It can detect whenever this beam is blocked. You will drop a piece of clear plastic
with evenly spaced black bars on it, called a Picket Fence. As the Picket Fence passes through
the Photogate, the LabPro or CBL 2 interface will measure the time from the leading edge of one
bar blocking the beam until the leading edge of the next bar blocks the beam. This timing
continues as all eight bars pass through the Photogate. From these measured times, the program
will calculate the velocities and accelerations for this motion and graphs will be plotted.

PRELIMINARY QUESTIONS
1. Inspect your Picket Fence. You will be dropping it through a Photogate to measure g. The
distance, measured from one edge of a black band to the same edge of the next band, is
5.0 cm. What additional information will you need to determine the average speed of the
Picket Fence as it moves through the Photogate?
2. If an object is moving with constant acceleration, what is the shape of its velocity vs. time
graph?
3. Does the initial velocity of an object have anything to do with its acceleration? For example,
compared to dropping an object, if you throw it downward would the acceleration be
different after you released it?
PROCEDURE
1. Fasten the Photogate rigidly to a ring stand so the arms extend horizontally, as shown in
Figure 1. The entire length of the Picket Fence must be able to fall freely through the
Photogate. To avoid damaging the Picket Fence, make sure it has a soft landing surface.
2. Connect the Photogate to the DIG/SONIC 1 input of the LabPro or the DIG/SONIC input on the
CBL 2. Use the black link cable to connect the interface to the TI Graphing Calculator.

1) The document describes an experiment conducted by students to investigate Faraday's Law of magnetic induction using a data logger. The experiment involved dropping a magnet through a coil of wire and measuring the induced electric field with a PC oscilloscope.
2) The results from the experiment showed both positive and negative voltages being generated as the magnet passed through the coil. This is because the leading and trailing poles of the magnet induce electric fields in opposite directions, according to Faraday's Law.
3) Using data loggers in science experiments provides advantages like automated and accurate data collection over long periods without human intervention. It also saves time and allows experiments to be repeated efficiently.
Report data logger (gas pressure sensor)syamimiauni18
This document discusses using a data logger to analyze the effect of particle size on reaction rate. An experiment was conducted using Alka-Seltzer tablets of different sizes added to water, while measuring the carbon dioxide produced over time. The results showed that smaller tablet particles produced carbon dioxide at a faster rate, as smaller particles have a larger total surface area, allowing for more frequent collisions and a faster reaction. In conclusion, data logging provides an effective way to automatically collect and analyze experimental data on factors that influence reaction rates.

It is easy to make the assumption that the only determinant of a successful business is profitability, especially from the outside. Apparently, profitability makes way for the expansion and keeps a company competitive (Cook & Cripps, 2005). That means that there are several factors that profitability depends on perfect commodity; teams with proper communication; and workers with high motivation, properly trained and committed to the organizational goals.

This project aimed to compare the use of and resultant errors when Measurement Fusion (Plot Fusion) and Track Fusion were used to combine data from various sensors in a simulated environment analogous to the Singaporean environment. The environment and analysis was done wholly using a program executed by MATLAB 6.1, and results showed that Measurement Fusion was more accurate when tracking objects following a path with many turns. However, the major source of error was not the fusion algorithm, but the inclusion algorithm.

Rolling
Apparatus
In this experiment a sphere, disk, and cylinder are rolled down an inclined plane
with a raised guide to keep it on the track. Two photogates are positioned over the track
to measure the velocity of each object at the position of each photogate. Each photogate
only records the elapsed time between the when the object enters and leaves the
photogate. The experimenter must determine the width d of the object as seen by the
photogate detector to determine the velocity through each photogate.
Theory
Velocity is the time rate of change of position of an object. If the width, d , of an
object and the time, t , it takes to pass a point are both known, the average velocity is

(1)
Angular velocity is the time rate of change of the angle of a rotating object,
measured in radians per second (rad/sec). For an object that rolls without slipping the
angular velocity is related to its linear velocity as
v d
R R t
(2)
The resistance of an object to a force (the inertia of an object) is caused by the
object’s mass. The resistance of an object to a torque (a force that causes a rotation) is
caused by the object’s moment of inertia (which is related to the object’s mass and how
far the mass is from the axis of rotation: 𝐼~𝑚𝑅2). This is why when a figure skater on
ice brings in her arms she rotates faster—her moment of inertial is smaller because more
of her mass is closer to her body (her effective radius decreases). Decreasing the moment
of inertia makes it easier for her to rotate (her rotational inertial decreases).
Objects in motion possess kinetic energy K . If the object is rolling it has kinetic
energy due to the forward motion of its center of mass,
CM

Notice that we have derived the parallel-axis theorem: 𝐼 = 𝐼𝐶𝑀 + 𝑀ℎ

situation for this lab, the object rolls about an axis at the point where it touches the ramp,
thus ℎ = 𝑅.

Total station is a surveying instrument that combines an electronic distance meter (EDM), an electronic theodolite, and a microprocessor. It can measure horizontal and vertical angles as well as sloping distances to target objects. Total stations provide accurate linear, angular, and elevation measurements and allow for automated data collection in the field. They have largely replaced traditional surveying equipment like tapes, levels, and transits due to their increased speed, accuracy, and capabilities.
The document compares vibrotactile feedback for navigation using a head-mounted device versus an abdomen-mounted device. It discusses prior research showing the head is more sensitive to vibration than the abdomen. An experiment was conducted with 9 participants performing a simulated navigation task with both devices. Results showed the head-mounted device had greater accuracy, shorter completion times, and faster response times, though some participants found it less comfortable. The study provides insights into whether a head-mounted or abdomen-mounted tactile display is better for navigation assistance.
The document is a fieldwork report for a site surveying course that describes a student group's experience conducting a closed traverse surveying project on campus. The objectives of the project were to gain experience using surveying equipment in the field and understanding traversing procedures. The group measured angles and distances between stations to collect traversing data. During analysis, they discovered errors in their data recording and had to discuss and apply formulas to calculate internal angles and make corrections. The experience provided the students hands-on practice with field equipment and improved their teamwork and understanding of traversing concepts and calculations.

4. 1 INTRODUCTION
„How science works‟ can be a difficult topic to tackle in a meaningful and interesting way.
As Cleaves and Toplist have identified , high stakes assessment seems to have led to pupils
carrying out a limited range of investigations in which they see little benefit. „How science
works‟ runs the risk of being a long list of disjointed facts or competences that are abstract in
pupils‟ minds and are poorly understood and remembered. Data logging is a fantastic way to
collect real data, quickly, for the whole class to see. One way to use it is to set up an
experiment on the front bench with the data logger connected to the teacher‟s PC and display
a chart using the data projector. It allows you and the class to focus attention on the scientific
questions that lead to the development of more reliable data and a better understanding of
what is going on. It is quick, visible to all and the chart builds while the experiment is in
progress.
The research of Hanley suggests a need for greater use of interactive techniques to
elicit student contributions. This approach provides an unrivalled opportunity for pupils to
discuss both physics and measurement and to develop and refine an investigation. Whereas
pupils boiling a beaker of water, recording a table of results and plotting a graph can take a
whole lesson, logging and charting the temperature of a kettle of water can be done in five
minutes. Then the chart can be discussed, a hypothesis formed and a follow-up experiment
carried out in a further ten minutes. The spotlight can move from the measurements to the
explanation or the investigation. Often, in pupil experiments, the interpretation of results is
neglected by pupils who have spent the whole lesson collecting data: they have simply run
out of time. This particularly affects the less able or less confident ones.
Data logging is also ideal for gathering multiple sets of data concurrently in real time,
something that is not possible in traditional school experiments. For instance, you can
measure the temperature of the water and the air inside a kettle, the outside surface
temperature and the noise made by cavitation. Then you can relate the measurements to each
other. Best of all, the whole thing can be done in less than ten minutes. By distributing the
charts electronically you can quickly provide engaging homework that is thought provoking,
highly diagnostic and quick to mark. It can also provide a framework for personalized
learning around a common task. Data logging composed of 3 important items which are
computer, data logger and sensor.

5. 2 ENGAGE
Engage is the first step taken to unearth information and existing knowledge of the students
on the topic that we will experiment. For example, we want to carry out the experiment
related to the effects of angle to acceleration and velocity. The first will show photo related
angle, acceleration and velocity. In this example, we show a picture of people cycling uphill
and downhill. After they looked into the picture, question “Which cycler is faster and easy” is
asked to the students. From their answers, we can find out their prior knowledge about the
issue, after that we should explain the real condition follow by next step to prove our
explanation. In this stage also, problem statement is created:
“Does the inclined track with a certain angle affect the acceleration and
velocity of a moving object?”
3 EMPOWER
This stage is the planning and doing stage in our experiment. We carry out an experiment
using data logger (motion sensor) to test the problem statement.
Title :
Acceleration And Velocity - Cart on an inclined track with different angles
Objective
To investigate how the acceleration and velocity of an object down an inclined tract
depends on the angle of the inclined tract by using the motion sensor.
Determine the angle of the inclined track for each different height, h
Use the software to plot the graph of position, velocity, and acceleration versus time
for each trial.
Introduction
Acceleration is the rate of change in an object‟s velocity. Since velocity is the speed and
direction of an object‟s motion, acceleration can mean speeding up, slowing down, or
changing direction. Constant acceleration occurs when an object experiences a constant net
force. Constant acceleration means that an object‟s velocity is constantly changing, but at a
uniform rate. For inclined track with higher angle, the acceleration of the moving object will
certainly higher but constant value; thus the velocity that depends on the acceleration will
also increase.
5
6. Theory
A cart on an inclined tract will roll down the tract as it is pulled by gravity. The direction of
the acceleration due to gravity is straight down as shown in the diagram. The component of
the acceleration due to gravity which is parallel to the inclined surface is g sin θ where θ is
the angle of the inclined tract. Neglecting friction, g sin θ is the acceleration of the cart.

Discussion
a. Describe the situation where an object slide down at different inclined angle and the
forces that involved in it.
Object placed on an inclined plane will always slide down. The rate of the object
sliding down the surface is depends on how tilted the surface is; or how big the
inclined angle is. The greater the inclined angle, the greater the acceleration. Objects
are known to accelerate down inclined planes because of an unbalanced force. For
object on inclined plane, there always at least two forces acting that are the force of
gravity and the normal force. The normal force is always directed perpendicular to the
surface.
Two forces acting:
The force of gravity and
the normal force
11
12. b. What are the forces that acting upon an accelerating object on inclined track and draw a
diagram to show the forces, plus state how the acceleration is formed?
The normal force and the gravitational force
Component parallel to
the plane, mg sin θ
Component
perpendicular to the
plane, mg cos θ
The gravitational force‟s component perpendicular to the plane is directed opposite
the normal force and as such balances the normal force. While the parallel component;
is not balanced by any other force. Therefore, object on the plane will subsequently
accelerate down due to the presence of an unbalanced force. It is the parallel
component of the force of gravity that causes this acceleration.
c. From the result, describe how the acceleration is affected by different inclined angles?
The acceleration due to gravity, g, has a constant value of 9.8m/s2. Gravity accelerates
objects down the inclined plane. But not the full force of gravity; only the component
of gravity, mg sin θ, act along the plane accelerates the object. The size of incline
angle can affect the object‟s acceleration down the inclined plane. As the angle
increase, the component of force parallel to the incline plane increase, and the
component perpendicular to the incline decrease and vice versa.
As the θ increase,
-mg sin θ increase
Component parallel to Component -mg cos θ decrease.
the plane, mg sin θ perpendicular to the
plane, mg cos θ
12
13. d. What are the constant variables in this experiment?
The gravitational force g and the mass of cart used, m, is the constant variables.
e. What precaution/ precautions you took when doing this experiment?
In this experiment, we use the motion sensor to detect the motion of the cart down the
inclined plane. The sensor is sensitive to any motion. Before releasing the cart, it must
not hold where the motion sensor can sense the movement of your finger. The cart
should be just released and not by applying any force. The motion sensor also must be
directed parallel with the plane. To obtain the best result, several trials and take the
best smoothest graph plotted by the computer.
Experiment’s conclusion
The acceleration of the cart is affected by the angle of the inclined plane. The bigger
the angle; the greater the cart‟s acceleration. This is because of the “parallel to plane”
gravity component; mg sin θ which is the acceleration of cart increase as the angle
increase.
The angle of the inclined plane is determined by using Pythagoras theorem
Using the data logger from the Data Studio software, the graph of position, velocity,
and acceleration versus time is plotted automatically.
4 ENHANCE
This stage is about how the concept has been applied in life. The acceleration that increase
with the angle of inclined plane concept has been apply in our daily life without many people
notice the principle that work behind it. For example: Cycling downhill or driving downhill
without extra energy or power. Most of the times, we can even stop using energy or power to
cycle and drive downhill but control the speed that resulted from the increase of acceleration
due to gravity in inclined area. Another example is the flow of river water is faster at the
upstream compared to the downstream.
The application of inclined plane, which is one of the six classical simple machines,
has been used when we move up or down the goods from a lorry or a higher place. Moving
an object up an inclined plane requires less force than lifting it straight up, at a cost of an
13
14. increase in the distance for the object to move. Wheelchair ramp and cable railway are two
of the inventions from the inclined plane concept.
The concept of increasing acceleration with increasing in angle of inclined plane has
been practices; when the goods are moving upwards using the inclined plane, the distance to
travelled is increasing using a longer inclined plane so that inclined angle become smaller and
the force to push it upward become smaller, while when goods are moving downwards, a
shorter distance inclined plane is used to increase inclined angle, thus increase the force due
to gravity and smaller force needed to push it downward or just to control the acceleration of
goods.
The concept of increase in angle of inclined plane also used in playground sliding,
winter sliding, and a lots more applications.
5 UNIQUE FEATURES OF THIS ACTIVITY
a. The position, velocity and acceleration of the cart can be determined and measured
accurately using the motion sensor. This is different from the traditional ways where the
ticker timer and ticker tape are use to measure the position, velocity and acceleration of
the cart manually when lots of calculation and graphs are needed to calculate and plot
before we can directly determine slope from the graphs and discuss the result obtained.
b. Three different graphs can be plotted at the same time.
c. Less work needs to be done by the students. The students do not need to do a long list of
calculations and pieces of graph papers.
d. Discussion can be take part after the experiment without wasting more time to do the
analyze process as the slope of graph can be determine directly using the tools in data
logger.
e. The changes of the data and graph can be observed immediately, allowing students to
make any changes or detect and overcome any errors in the experiment.
f. The experiment can be repeated many times to obtained the accurate readings.
6 CONCLUSION
Each of these experiments was very quick and easy to set up plane, retort stand, a data logger
and some sensors. Using the simplest mode of operation of the software means that almost no
knowledge or experience of data logging is required. Press green for go and red for stop. This
can be a straightforward way to introduce data logging to our lessons and build familiarity
and confidence with the hardware and software. The wealth of data helps children to focus on
14
15. the patterns in the graphs and what they mean in terms of physics, and to develop chart
reading skills. Above all the data prompts questions from the pupils, arousing their curiosity
and providing opportunities for them to develop investigative strategies to answer those
questions. The speed of data collection with data loggers allows many of these questions to
be quickly answered by rerunning the experiment with simple variations, adjusting sensor
positions, physical conditions or adding sensors. It also focuses pupil attention on details of
experimental setup such as the exact location of the sensors.
The value of electronic data also shows itself in the ease with which it can be shared.
It can be e-mailed to absent pupils or to the whole class and pupils can easily augment it by
labeling a chart in Word or reprocessing the data in Excel (or the original software). It can be
transferred to PowerPoint and worked on collaboratively in small groups. Data logging
enables the more able to handle data in more sophisticated ways. The less able can focus on
the meaning of the data rather than simply plotting it (a high-level task) as well as completing
well-presented work that they can be proud of and that will be worthy of display.
