 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)
