1. Before you make the graph of PE and KE over time, what shape should you
expect? And why?
PE should decrease over time while KE should increase over time. The shapes should

1. Compare the two methods of adding vectors. Make sure you discuss major benefits
as well as major problems with each.
There are two methods to adding vectors. One is to graphical

1. We assumed the cylinders were point masses for calculating inertia. We could have
used the parallel axis theorem to do better. Test this for the two masses in hole 1 and

1. (a) How large are your errors in p? Do they meet your expectations? Why?
The errors in p ranged from 11.29% to 56.76%. The higher percentage occurred in the elastic
collision of

1. What was our goal for each of these two experiments?
Our goal for both of these experiments was to verify experimentally that the acceleration
of gravity is -9.8 m/s2.

1. Given a liter of water just at boiling, how much energy does it take to boil it all?
In order to solve this, the equation, Q=mcT, is used. The mass is 1 kg as 1 L is equivalent
