Momentum

MOMENTUM - The quantity of motion of an object, calculated as the product of its mass and velocity; a vector quantity.

IMPULSE - The product of force and the time over which it acts, equivalent to the change in momentum of an object.

IMPULSE-MOMENTUM THEOREM - States that the change in momentum of an object equals the impulse applied to it.

LAW OF CONSERVATION OF MOMENTUM - States that in an isolated system where the net external force is zero, the total momentum remains constant.

COLLISIONS - Interactions between two or more bodies causing changes in motion due to internal forces.

ELASTIC COLLISION - A collision where both momentum and kinetic energy are conserved.

INELASTIC COLLISION - A collision where momentum is conserved but kinetic energy is not.

PERFECTLY INELASTIC COLLISION - A collision where objects stick together after impact, moving with a common velocity.
