Collision Characterization
Purpose and Scope
The purpose of this lab was to run a series of simulated collisions, to build up a database of
collision information that can guide engineers during the real mission. Our objective of this lab
was to find whether the momentum was conserved during the collisions, analyze whether the
collisions were elastic and compare the soft collision vs. the hard collisions for each item
mentioned above.
Theory
In this lab we used multiple equations to obtain the proper values and data that we needed. We
began by verifying the conservation of momentum by using the following formula P1x=P2 x.
The formula when written out is as follows m∗v1x+m∗v1 x=m∗v2x+m∗v2x . However, our
masses are the same therefore they cancel out. We used the same formulas for the y component,
it would be written as follows P1 y=P2 y . Here is the long version
m∗v
1 y+m∗v1 y=m∗v2 y+m∗v2 y . Once we found that information, we analyzed the total
kinetic energy of the system before and after the collisions to determine whether they were
elastic using the following equation Ki=Kf . The equation can also be written as

with the velocity component calculated as v=√vx 2+v2y
. Then we verified Newton’s third law using the following formula F1=−F2 . The F was
calculated using the following equation F=√F2x+F2y . We used the exact same formulas listed
above for the soft collision as well.
Methods
As usual, the camera was able to locate the position of each surface at the time of measurement
due to the specific colored sticker on the center of the pucks. We began the lab by two of us
getting on opposite ends of the frictionless table and releasing the pucks directly toward each
other, to create a collision. We did this for both the hard and soft collision. Once, we had the data
points we proceeded to analyze our graph and then use the following equations listed above to
find the data we needed. Although ga
