Time Uncertainty
The uncertainty in time remains the same for part 2.
Gravity can be determined by comparing acceleration and mass ratio. Theoretically, this number should not be significantly different than the local gravity calculated in lab 1.
Gravity was determined in lab 1. “Free Fall”, using Google earth, and is shown below.
The local gravity of the laboratory was necessary to take into account because depending on where the location is on Earth the gravity deviates from 9.8m/s2.
λ =38.020905˚ a=5.278895*10-3 β= 2.3462*10-5 ge= 9.7803185 ms-2
Local gravity (g)= 9.799m/s2 + .001m/s2
This information was obtained from the online Appendix F and Google Earth.
The uncertainty of Gravity was obtained by plugging in the givens, ge, β, and a in the equation above then finding the latitude and longitude for a location within 10 miles east and 10 miles west of where the actual experiment took place. Each value was subtracted from the actual local gravity then standard deviation was used to find the uncertainty.

There was a transfer of momentum from the car to the track during the trials. Every time the cart would come in contact with the barrier the track would shift slightly. Also the barrier would move back and forth when the cart would hit it. There is also some friction on the cart that cannot be accounted for. When the spring on the cart compresses against the barrier, energy escapes the system causing the kinetic energy in the backward direction to be less than the forward direction. Correcting this error would be a very difficult task. In order to do so the team would have to lock the track to the table, which would have to lock to the floor, the floor would have to lock to the ground, and the ground to the Earth. This would be an almost impossible task.
Questions:
1.) According to Graphs 1-3 (displacement vs. time) all 3 graphs indicate that the velocities were comparatively constant in both the forward and backward direction. This was true because the slope of the line was
