1

Momentum

Is the system closed? What does closed sytem mean? What other forces are acting?

187

7

Momentum and Impulse

Look at Newton's 2nd law, momentum version

188

1

Conservation of Momentum

Definition of momentum

188

2

Conservation of Momentum

Newton's 2nd law, momentum version, solve for Dv

188

15

Collisions and Impulse

Newton's 2nd law, momentum version

188

17

Collisions and Impulse

Symmetrical problem, vertical momentum doesn't change so there is no vertical impulse

189

22

Elastic Collisions

No outside forces so momentum conserved, elastic so kinetic energy conserved (look at equation 7-7 for a simplified version)

Inelastic Collisions

Useful for Next Lab DELETED, I WILL SOLVE THIS PROBLEM IN CLASS

Center of Mass

Use Eq. 7-9a, extended to three particles.
