Describe elastic collision and what is conserved
|
Objects collide and separate
Total momentum and KE |
|
|
Describe general inelastic collision and what is conserved
|
Objects collide and separate unless perfectly inelastic
Only momentum |
|
|
Describe perfectly inelastic collision and what is conserved
|
Objects collide and stick together
Only momentum |
|
|
How do you determine an inelastic versus elastic collision?
|
KE must be calculated because momentum will be conserved and only a difference in KE can tell whether some energy is no internal, noise, heat

Trick problem for incline planes:
What is another way to say mg*cos(30) |
mg*sin(60)
MCAT will switch sin/cos and then use complementary angle |
|
|
Do real pendulums follow SHM?
|
No, the restoring force is not equal to mgsin(theta). However if theta is small the restoring force can be appximated to mg*theta (in radians)
