0:22 Conservation of Mechanical Energy
0:54 Work due to Friction equals Change in Mechanical Energy
1:30 Net Work equals change in Kinetic Energy
3:01 Conservation of Momentum does NOT require the work due to friction to be zero
3:28 The initial and final points when dealing with momentum are predetermined
3:56 Impulse does not equal Impact Force
