1 Multi-Particle Systems 0

2 Center of Mass Variables

3 Transformation of Reference Frames Define Center of Mass Frame where P new =0

4 Why Do This? For an N particle system, there are 3N coupled equations! reduces number of equations by 3. Ifthen Can go to Center of Mass frame where To get back to this frame, addto all particle velocities

5 Two Particle Systems Center of Mass Frame In CM frame: At center of mass: Still may have angular momentum.

6 Multi-Particle Systems Angular Momentum 0 Q 00
