Pulley Cart

In physic class, we get to play around with the pulley carts with 3 metal coins inside them and also a ticker-tape timer. The purpose of this lab is to show and prove the relationships between acceleration, total force and the mass.

The metal pieces are tied to the strings to act as the force that pulls the cart across the table until the distance traveled equals the height of the table. At the same time, the ticker-tape is used to record the pattern of acceleration of the different trials.

After the entire experiment, 5 different tapes are generated from the timer and are used for later analysis and calculations.

Data for 6 Scenarios:

1) acceleration vs. force 1

d1=0.008 m d2=0.03 m dt=0.24m

t=1/30 s t=1/30 s a=1.6m/s ^2

v1= 0.24 m/s v2=0.9m/s

2) acceleration vs. force 2

d1=0.029m d2=0.09 m dt=0.58m

t=1/30 s t=1/30 s a= 5.6 m/s ^2

v1= 0.87 m/s v2=2.7m/s

3) acceleration vs. force 3

d1=0.035m d2=0.073 m dt=0.35m
