I need help developing a conclusion,

thank you for the help!

Here's my discussion from the lab:

During this experiment we observed collisions between two carts bumping against each other on a track. For this procedure, we demonstrated two trials each of a magnetic bumper collision, Velcro bumper collision, and then a Velcro to magnetic bumper Collison. In these trials we wanted to determine whether the collisions were elastic (kinetic energy preserved), inelastic (kinetic energy absent), and or completely inelastic (the carts stick together). That being said, we wanted to classify these types of collisions and measure the energy alteration while testing the conservation of momentum from our data. Gathering our velocities and data via logger pro, applied to each trial we first placed a motion detector at each end of the track while resting cart two in the middle and then releasing cart one. In the first two trials of the magnetic bumpers collision, we observed that both carts stuck together each time and remained super inelastic with the kinetic energy lost. Within the Velcro bumper collision, this trial also lost its kinetic energy, but we noticed it wasn’t as super inelastic as the magnetic bumpers were, classifying this as only inelastic. Lastly in the Velcro to magnetic collision, this collision was quite the opposite from the first two. The carts bumped against each other, conserving the kinetic energy and making this trial elastic.

Heres my data:

Explanation / Answer

Magnetic bumper collision

In this case both kinetic energy and momentum is conserved, hence it is elastic collision.

Velcro bumper collision

In this case also the kinetic energy is not conserved while momentum is comparitively conserved, hence this is ineleastic collision.

Velcro-Magnetic bumper collision

In this case both carts stuck together each time and remained super inelastic with the kinetic energy lost. Hence this is the case of inelastic collision.

Hence from these it can be concluded that in case of elastic collisions both kinetic energy and momentum are conserved. Whereas in case of inelastic collision only momentum conservation is observed.
