Questions:
1. Should momentum be conserved for both elastic
and inelastic collisions?
List at least
three different reasons that is wasn’t completely conserved.
2. Should kinetic energy be conserved for
elastic collisions? _____
Should it be conserved for inelastic
collisions? _____
Compare the % change for elastic and
inelastic. Did it seem to follow in
theory what should happen?
