Acceleration is the rate of change of an object's velocity. An object accelerates any time its speed or direction changes. Positive acceleration occurs when speed increases, while negative acceleration occurs when speed decreases. Acceleration is calculated by dividing the change in velocity by the time interval over the change occurred. Amusement park rides like rollercoasters produce high speeds and accelerations through steep drops and loops that accelerate riders via gravity, as well as sharp turns that accelerate riders towards the sides of cars.

speed and velocity

This document discusses speed, velocity, distance, and displacement. It defines these terms and distinguishes between them. Speed is a scalar quantity referring to the total distance traveled over time, while velocity is a vector quantity that includes direction of motion. Distance is the total length of travel regardless of direction, while displacement refers to the distance moved in a particular direction. Examples are provided to illustrate these concepts, including a discussion of constant speed but changing velocity when moving in a circle. Graphs of distance over time are also used to represent speed.

Momentum

Momentum is a quantity that expresses the motion of a body, equal to the product of its mass and velocity. The momentum of an object depends on its mass and velocity, with greater mass or velocity resulting in more momentum. The law of conservation of momentum states that in a closed system without external forces, the total momentum before and after an interaction will be the same. Examples include a person recoiling after firing a gun or moving backward when throwing an object off a skateboard. In collisions, the total momentum of the system is conserved and can be expressed mathematically as the sum of the momentum of the objects before equalling the sum after.

Balanced and Unbalanced Forces

Forces can be pushes or pulls and are measured in Newtons. A net force is the combination of all forces acting on an object. An unbalanced net force will cause a change in an object's motion, while a balanced net force will not. Friction and air resistance are types of forces that oppose motion. Gravity is an attractive force between objects that depends on their masses and distance between them. Newton's second law relates force, mass, and acceleration.

Speed and velocity

Speed refers to how fast an object moves over a period of time, while velocity also considers the direction of motion. When describing storms, forecasters provide both the speed and direction it is moving, as well as the circular speed of the winds. The circular wind speed determines the storm's strength. Instantaneous speed refers to an object's speed at a single moment, while average speed considers the total distance and time over multiple moments. Motion is considered constant if the instantaneous speed remains the same over time.

Graph of The Motion

This document discusses position vs. time graphs and how they can be used to represent motion. It explains that position is plotted on the y-axis and time on the x-axis. A straight line on the graph indicates constant speed, and the steeper the line, the faster the speed. The slope of the line equals speed, as it represents the ratio of change in position over change in time. Position vs. time graphs and their analysis can provide speed information without direct measurement.

Forces

A force is any push or pull that can cause an object to change its motion. Forces have both magnitude and direction. There are two types of forces: contact forces, which require objects to touch, like friction or tension; and non-contact forces, which act over a distance, like gravity or magnetism. A force is measured in Newtons, and the acceleration due to gravity on Earth is 9.81 m/s2. Forces can cause objects to accelerate, decelerate, or maintain a constant velocity depending on whether the net force is nonzero.

Newton's second law of motion

Newton's second law of motion states that the acceleration of an object depends on the mass of the object and the net force acting upon it. An unbalanced net force is required to change the velocity of an object, with greater net forces producing greater accelerations. The relationship between force, mass, and acceleration is expressed by the equation Force = Mass x Acceleration.

- Acceleration is a change in velocity over time. It is a vector quantity measured in meters/second squared. Positive acceleration means speeding up while negative acceleration means slowing down.

Waves and Energy

Waves can transfer energy from one place to another. There are two main types of waves - mechanical waves, which require a medium and can only travel through matter, and electromagnetic waves, which can travel through vacuums. The key characteristics of waves include wavelength, frequency, amplitude, crest, and trough. Mechanical waves can be transverse, with oscillations perpendicular to the direction of travel, or longitudinal, with oscillations parallel to travel. Sound waves are an example of longitudinal mechanical waves.

This document discusses distance-time graphs, velocity-time graphs, and standard units for physical properties. Distance-time graphs show steep lines for fast speeds, shallow lines for slow speeds, and flat lines for zero speed. Velocity is calculated from the gradient of a distance-time graph. Velocity-time graphs show increasing, decreasing, or constant speed. The area under a velocity-time graph equals the distance travelled. Common units for physical properties like distance, time, speed, and mass are also listed.

Motion graphs practice

The document discusses position-time graphs and velocity-time graphs. It explains that a flat line on a position graph represents an object that is stopped, a sloping line represents constant speed, and a curved line represents changing speed or acceleration. It provides similar explanations for velocity graphs. The document asks questions about interpreting and constructing graphs, determining speed and velocity from graphs, and calculating displacement from a velocity graph.

Carbon cycle

Carbon is an essential element that cycles between the atmosphere, ocean, organisms, and geologic reservoirs as part of the carbon cycle. Photosynthesis incorporates carbon from the air and water into organic compounds, while respiration and decomposition release it back. Fossil fuels like coal and oil were formed from ancient plant and algae remains over millions of years. Burning fossil fuels returns carbon to the air, and limestone erosion also adds carbon back to the cycle through weathering. The carbon cycle continuously moves carbon between the biosphere and geosphere.

This document discusses sources of error in measurement and the importance of accuracy. It explains that random errors can cause inconsistent readings and averaging repeated measurements can reduce these errors. Common sources of error include instrument errors, non-linear relationships in instruments, errors from reading scales incorrectly, environmental factors, and human errors. Taking the average of multiple readings eliminates random variations between readings and provides a more accurate result.

MOTION

The document discusses various concepts related to motion including:
- Motion depends on the point of reference used and can be relative.
- Distance is the total length traveled while displacement is the straight line distance between initial and final positions.
- Speed is the rate of change of an object's position with time, while velocity includes both speed and direction of motion.
- Acceleration is the rate of change of velocity with time and can be positive (increasing velocity) or negative (decreasing velocity).
- Graphs of displacement vs time and velocity vs time can provide information about an object's motion like speed, acceleration, and distance traveled.

ACCELERATION.pptx

Acceleration is defined as the rate of change of an object's velocity. An object accelerates when its speed changes, its direction changes, or both change. Positive acceleration occurs when speed increases, while negative acceleration occurs when speed decreases. Even if speed stays the same, an object accelerates when its direction changes, such as when rounding a curve.

It defines key terms like displacement, speed, velocity, acceleration, frames of reference, and describes the relationships between distance, time, speed, velocity, and acceleration using formulas and graphs. It also discusses one-dimensional and two-dimensional motion and how gravity affects vertically moving projectiles.

Acceleration

Acceleration describes how an object's velocity changes over time. An object accelerates when its speed changes, its direction changes, or both its speed and direction change. Acceleration is calculated by taking the change in velocity and dividing by the time elapsed. Common examples of acceleration include objects falling due to gravity, objects moving in circles due to centripetal force, and vehicles changing speed.

Motion Notes PPT STUDENT KEY.pdf

The document discusses key concepts related to motion including distance, displacement, speed, velocity, acceleration, and free fall. It defines these terms and provides examples to illustrate them. For instance, it explains that displacement refers to how far an object is from its starting point, while distance describes the total length traveled. It also discusses that acceleration can change in different ways such as increasing or decreasing speed, changing direction, or altering both speed and direction simultaneously. Free fall acceleration on Earth is specified as 9.8 m/s2 due to gravity.

MOTION.pptx

After going through this module, you are expected to:
describe the motion of an object in terms of distance or displacement, speed or velocity and acceleration (S7FE-IIIa-1);
perform activities on speed, velocity and acceleration; and
compute for the speed, velocity and acceleration.

Acceleration ( 1 )

Acceleration refers to the process of an object changing its speed, whether by increasing or decreasing speed, or changing direction. An object accelerates when its speed increases over time. An object also accelerates when its speed decreases, which is called deceleration or negative acceleration. Even objects moving at a constant speed accelerate if they change direction, like seats on a Ferris wheel. To calculate acceleration, you determine the change in speed over a period of time by taking the final speed minus the initial speed and dividing by the time elapsed.

Even objects moving at a constant speed accelerate if they change direction, like seats on a Ferris wheel. To calculate acceleration, you determine the change in speed over a period of time, with acceleration measured in meters per second squared.

Force and motion

This document discusses forces and motion. It defines key terms like velocity, acceleration, and force. Velocity is how fast an object is moving in a direction, measured in meters per second. Acceleration is a change in velocity caused by an applied force and can be positive (speeding up) or negative (slowing down). Forces like gravity and friction are what cause changes in an object's motion by speeding it up or slowing it down. Graphs are used to visualize changes in position, velocity, and acceleration over time.

- 1. Acceleration Acceleration, Speed and Velocity Acceleration is the rate of change of velocity. When the velocity of an object changes, the object is accelerating. A change in velocity can be either a change in how fast something is moving, or a change in the direction it is moving. Acceleration occurs when an object changes its speed, it's direction, or both.
- 2. Acceleration Speeding Up and Slowing Down When you think of acceleration, you probably think of something speeding up. However, an object that is slowing down also is accelerating. Acceleration also has direction, just as velocity does.
- 3. Acceleration Speeding Up and Slowing Down If the acceleration is in the same direction as the velocity, the speed increases and the acceleration is positive.
- 4. Acceleration Speeding Up and Slowing Down If the speed decreases, the acceleration is in the opposite direction from the velocity, and the acceleration is negative.
- 5. Acceleration Changing Direction A change in velocity can be either a change in how fast something is moving or a change in the direction of movement. Any time a moving object changes direction, its velocity changes and it is accelerating.
- 6. Acceleration Changing Direction The speed of the horses in this carousel is constant, but the horses are accelerating because their direction is changing constantly.
- 7. Acceleration Calculating Acceleration To calculate the acceleration of an object, the change in velocity is divided by the length of time interval over which the change occurred. To calculate the change in velocity, subtract the initial velocity—the velocity at the beginning of the time interval—from the final velocity—the velocity at the end of the time interval.
- 8. Acceleration Calculating Acceleration If the direction of motion doesn't change and the object moves in a straight line, the change in velocity is the same as the change in speed. The change in velocity then is the final speed minus the initial speed.
- 9. Acceleration Calculating Positive Acceleration How is the acceleration for an object that is speeding up different from that of an object that is slowing down? Suppose a jet airliner starts at rest at the end of a runway and reaches a speed of 80 m/s in 20 s.
- 10. Acceleration Calculating Positive Acceleration The airliner is traveling in a straight line down the runway, so its speed and velocity are the same. Because it started from rest, its initial speed was zero.
- 11. Acceleration 2.2 Calculating Positive Acceleration Its acceleration can be calculated as follows:
- 12. Acceleration 2.2 Calculating Positive Acceleration The airliner is speeding up, so the final speed is greater than the initial speed and the acceleration is positive.
- 13. Acceleration 2.2 Calculating Negative Acceleration Now imagine that a skateboarder is moving in a straight line at a constant speed of 3 m/s and comes to a stop in 2 s. The final speed is zero and the initial speed was 3 m/s.
- 14. Acceleration Calculating Negative Acceleration The skateboarder's acceleration is calculated as follows:
- 15. Acceleration Calculating Negative Acceleration The skateboarder is slowing down, so the final speed is less than the initial speed and the acceleration is negative. The acceleration always will be positive if an object is speeding up and negative if the object is slowing down.
- 16. Acceleration Amusement Park Acceleration Engineers use the laws of physics to design amusement park rides that are thrilling, but harmless. The highest speeds and accelerations usually are produced on steel roller coasters.
- 17. Acceleration Amusement Park Acceleration Steel roller coasters can offer multiple steep drops and inversion loops, which give the rider large accelerations. As the rider moves down a steep hill or an inversion loop, he or she will accelerate toward the ground due to gravity.
- 18. Acceleration 2.2 Amusement Park Acceleration When riders go around a sharp turn, they also are accelerated. This acceleration makes them feel as if a force is pushing them toward the side of the car.
