What about Energy?
- “Elastic Collision” of two equal mass objects:
- Kinetic Energy: Before: (1/2)mv02 same as After: (1/2)mv02
-
- “Totally Inelastic Collision” - equal mass objects:
-
-
- Kinetic Energy: Before: (1/2)mv02 After: (1/2)(2m)(v0 /2)2 = (1/4)mv02 Kinetic Energy NOT the same after collision!
