6 Cards in this Set

  • Front
  • Back
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)
