This document outlines criteria for assessing student lab reports in physics. It provides detailed rubrics for evaluating observations and recordings of data, analysis and interpretation of results, organization of reports, and hypothesis testing in experiments. Key areas that will be assessed include precise measurements, clear presentation of data in tables and graphs, proper calculations, supported conclusions, identified sources of error, and use of safety precautions. Students will be scored based on demonstrating skills such as correct spelling, punctuation, logical sequencing of steps, and justification of conclusions using experimental evidence.
This paper seeks to serve as a guide to unconscious CAPE students who could use a push or central idea of what a Caribbean Studies internal assessment should look like.

PHYS 221 Lab 1 - Acceleration Due to Gravity
Please work in groups of three. Please submit one lab report per person via Canvas.
In this laboratory we will measure the acceleration due to gravity by studying the motion of a cart accelerating down an inclined plane.
Background
Suppose we start with a level track and then tip it, as shown in Figure 1 below. Let L be the distance between two fixed points on a ramp, selected to be as far apart as possible, on the track. Let h be the difference in the vertical height above the table of these two points.
Figure 1 - Schematic of a cart on an inclined plane. The magnitude of the acceleration of the cart down the ramp can be considered a component of the gravitational acceleration: a = g sinθ
Then we have an incline of angle given by Equation 1:
. (1)
The acceleration of gravity, g, acts vertically downward, so the component of parallel to the incline – which is the acceleration of our cart – is given by Equation 2:
(2)
We see in Equation 2 that a graph of acceleration a as a function of sinθ should be linear with slope g. We will take data to plot such a graph and from its slope determine the value of g.
Setup
Gather the following materials:
· 2 m ramp
· Meter stick
· Lab Stand
· Ramp clamp
· Plastic Box with ULI, AC Adapter, and USB Cable
· Motion Sensor
· Magnetic Bumper
1. Connect the ULI to the computer via the USB cable and connect the AC adapter. Open Logger Pro 3.8.7.
2. Attach the ramp clamp to the lab stand and attach one end of the ramp.
3. Elevate one end of the track slightly using the vertical rod. Choose a value of h so that the angle of inclination stays less than about 8 degrees. (Use Equation 1 to verify).
· You can choose any two points along the track to serve as your L, but they must be the same two points for all your runs!
· Measure h by measuring the difference in the two heights of your two points.
4. Connect a motion sensor to the ULI and mount it on the elevated end of the track. The low end of the track should have a magnetic bumper installed on it (magnets face upward along the track).
Procedure
1. Choose at least five values of height h, to vary over the range 1-8 degrees.
2. Record each value of h chosen, and then obtain a graph of velocity versus time for that value.
3. You have two options for collecting velocity data from the cart:
· Release from the elevated end of the track and let it accelerate to the lower end.
· Push the cart from the lower end of the track up the incline. Record data during its entire motion back to its starting point. This will take slightly more finesse, but the data will be better.
The motion sensor will not record accurate data for a cart closer than 40 cm (the limit of its near range). Do not let the cart collide with the end of the track!
4. Determine the acceleration for the cart by using the Linear Fit tool and highlighting the appropriate region of the velocity graph. Record the .

FACE RECOGNITION ALGORITHM BASED ON ORIENTATION HISTOGRAM OF HOUGH PEAKSijaia
In this paper we propose a novel face recognition algorithm based on orientation histogram of Hough Transform Peaks. The novelty of the approach lies in utilizing Hough Transform peaks for determining the orientation angles and computing the histogram from it. For extraction of feature vectors first the images are divided into non overlapping blocks of equal size. Then for each of the blocks the orientation histograms are computed. The obtained histograms are combined to form the final feature vector set. Classification is done using k nearest neighbor classifier. The algorithm has been tested on the ORL
database, Yale B Database & the Essex Grimace Database.97% Recognition rates have been obtained for
ORL database, 100% for Yale B and 100% for Essex Grimace database

M 210 More drawing in LATEX February 23, 2016
Arcs
An arc of radius r from point (p,q) with initial angle ϕ (phi) and final angle ψ (psi) is drawn in
TikZ by the code
LATEX\draw (p,q) arc (phi:psi:r);
Note that TikZ does not require the center (a,b), which is often easier to determine that the arc’s
initial point. Polar coordinates (relative to the arc’s center) can be used to express the initial point
in terms of the arc’s center.
(a,b)
(p,q)
ϕ
ψ
r
p = a + r cosϕ
q = b + r sinϕ
In tikzpicture environment enter
\draw ({a+r*cos(phi)},{b+r*sin(phi)}) arc (phi:psi:r);
for the specific values of a, b, r, ϕ (phi) and ψ (psi).
LATEX
According to the TikZ’s manual, by default arcs are drawn in positive (counter-clockwise) direction,
assuming initial angle ϕ to be smaller than ψ. However, I have been able to draw arcs in negative
(clockwise) direction by choosing an initial angle larger than final angle.
Precise Label Positioning
The relative positions above, below, left, right, above left, above right, below left, and

following figures.

While it is possible to adjust the separation between label and node, it is not that easy to adjust
the angle (the above provide label placement only for angles in multiples of 45◦). The following will
work to place the label (that is its center) at the the indicated position: precise distance s at relative
angle θ from the position of the node.

To place label at the above mentioned position use the code (where θ is theta degrees):
M 210 — February 23, 2016 page 44
LATEX\draw ({nx + s*cos(theta)}, {ny + s*sin(theta)}) node {label};
To rotate the label as in the above illustration, use code:
LATEX\draw ({nx + s*cos(theta)}, {ny + s*sin(theta)}) node {\rotatebox{theta}{label}};
Special Triangles
In trigonometry the triangles with degrees 45-45-90 and 30-60-90 provide exact values for the trigono-
metric functions. It is quite easy to obtain the exact values of angles of 15 and 75 degrees from those
of 30 degrees by half- and double-angle formulas and other trigonometric identities, however, these
values can also be obtained from the following figure containing an equilateral triangle in a square
with sides equal to 2.
