C. Inelastic Collision
1.
Draw straight lines from the “point-of-contact” spot to the dots made by the ‘inelastic collision’ shot. (There
should be two lines.)
2.
Measure from the “point-of-contact” to each of the dots made by the ‘inelastic collision’ shot.
3.
Measure the angle from the centerline to the straight line for each dot of the ‘inelastic collision’ shot.
4.
Use the angle and the length of the lines for the shot to calculate the x-component and the y-component for
each ball in the ‘inelastic collision’ shot. Record the values.
5.
After the collision, add the x-momentum for Ball 1 and the x-momentum for Ball 2 and record the result in
Table 6.1 as “Final x-momentum”.
6.
Calculate the initial kinetic energy of Ball 1 and the sum of the kinetic energy of Ball 1 and Ball 2 after the
collision.
7.
Calculate the percent differences.
