Linear Momentum
Momentum and Its Relation to Force
Rate of Momentum
Conservation of Momentum
During a collision, measurements show that the total momentum does not change:
MaVa + MbVb = MaV'a + MbV"b
Collisions and Impulse
During a collision, objects are deformed due to the large forces involved
Conservation of Energy and Momentum in Collisions
Momentum is conserved in all collisions
KE is conserved is called elastic collisions
KE is not conversed is call inelastic collisions
Center of Mass (CM)
the center of mass lies closer to the one with the most mass
