Lab 11: Collisions

The goal: make some collisions with carts.  See if momentum and kinetic energy are conserved.

Let me start with two examples:

Now, what to do?

  • You want some carts to collide.
  • There are different things you can put on the front of the carts.  The red/blue carts have built in magnets on one side and the other has velcro and springy things.
  • What about an explosion?  Is momentum conserved there?
  • Does it matter if the carts are the same mass?
  • What about three collisions?
Really, the first thing you want to think about is how you will measure the speeds before and after the collision.  I will let you decide, but here are some options:
  • Photo gates (yes, we have these)
  • 2 motion detectors
  • Make a video and then do video analysis.
Yes, there is a vpython lab to go along with this.  I will post the documents in blackboard.
