Momentum and Its Relation to Force

Conservation of Momentum

During a collision, measurements show that the total momentum does not change:

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 image
