I think momentum will conserve in both elastic and inelastic collisions. In last lab, we conserved that both carts’
momentum came out to be almost the same. I think this time also will be conserved and it will be come out to be
same. So, if make a graph, I think it will become direct proportion. I think kinetic energy will not conserve in both elastic or
inelastic collisions because, I think some kinetic energy will emit.

List of problems.

1. Movement (slide) of additional weights on the cart.
・ We used cylinder shape weights for additional weights, so when the carts move, weights also moves
a little, so maybe this caused some change in velocity.

2. Swaying of cardboard.
・ We used piece of cardboard to make target bigger. It’s much harder than a paper but, it sway a little.
Because of this swaying, Motion detector may could not read some data properly.

3. Whey of we slide cart.
・ We make slide cart, it’s moved by a human hands so I think most error coming out from here.

4. Motion Detector problem
・It’s tricky to make the Motion Detector to work perfect. So maybe somethings blocked wave.

Aim ;
Are momentum and kinetic energy conserved in elastic and inelastic collisions?
Momentum 　 = Mass × Δvelocity　　　　 .P = MV
Kinetic Energy = 1／2 × Mass × (Δvelocity )　　　 KE = 1/2 MV
