Momentum Intro Momentum- The mass of an object multiplied by its velocity(inertia in motion). Formula: momentum= mass X velocity(momentum=mv) When direction is not a factor: momentum=mass X speed

Impulse The impulse is equal to the change in momentum. Formula: impulse= force X time interval

Bouncing Bouncing causes the impulses to be greater. Bouncing requires greater impulse because it needs enough momentum to make the object sto and then bounce back upward. In comparison the impulse is less without a bounce because it just stops and stays at rest.

Conservation of Momentum Law of conversation of momentum states: “In the absence of external force, the momentum of a system remains unchanged.” Conserved: when momentum does not change.

Collisions Elastic collisions-colliding objects bound or rebound without lasting deformation or the generation of heat. This creates a perfect bounce. Such as billiard balls colliding. Inelastic collisions-colliding objects become distorted and generate heat. Such as freight trains colliding.

Momentum Vectors Direction of colliding objects effects the resulting momentum and direction. For example a car due north collides with a car due east at equal momentum will progress in the north east direction.
