1. Three points in a constant
The reason for this is because; the image height (h i) is inversely proportional to
the distance between the pin-hole and the object (d o) while the image height (hi)
is directly proportional length o
Slope of chord at point t=0.3s and point t=0.7s
= x2-x1/t2-t1
= 27-7/0.7- 0.3
= 50 cm/s
Slope of tangent of curve at point t=0.5s
= x2-x1/t2-t1
= 30-15/0.8- 0.5
= 50 cm/s

In this experiment the objective was to have a very small percent error between the total initial
momentum and the total final momentum, because theoretically the momentum should be

The purpose of this lab was to replicate the human arm through the use of levers, weights and

In the first part of this lab, the acceleration vectors were obtained by subtracting
displacement vectors (x) and dividing by (t)2.
From the 5th spark to the 15th spark, the acceleration was

Newtons second law was verified experimentally by using a glider on a frictionless air track, which was

Discussion
Based on our graph, it is clear that the range of the ball increases as the height of launch
increases, due to the acceleration of gravity. We originally thought there would be a direct

Abstract
Newtons second law is Fnet=Mtotal a.
Therefore a= Fnet /Mtotal
For the atwood machine, Fnet is also equal to the difference in weights : (M)g
Mtotal is also equal to 2M + M

The objective of this lab was to experimentally determine the resultant of several vector
