A2L Item 262

Goal: Hone the concept of a collision

Source: CT151.2S02-43

A cart
of mass m is moving with speed v. Is it possible for the kinetic energy
or the momentum to be larger after a collision?

  1. No; it is impossible
  2. Yes; the kinetic energy can be larger
  3. Yes; the momentum can be larger
  4. Yes; both can be larger



(4) Many students get fixated on the idea that all collisions are head
on and cause the object to lose energy and momentum.
