Momentum, Impulse, Collisions and Center of Mass
Review for AP Physics C: Mechanics (11:41)
Calculus based review of conservation of momentum, the momentum version of Newton’s second law, the Impulse-Momentum Theorem, impulse approximation, impact force, elastic, inelastic and perfectly inelastic collisions, position, velocity and acceleration of the center of mass of a system of particles, center of mass of a rigid object with shape, and volumetric, surface and linear mass densities.
