Momentum

The difference between the final and initial values of momentum; the mass times the change in velocity

• Impulse-momentum theorem

• Impulse

• Change in momentum

• Angular momentum

Collision in which objects separate after impact and kinetic energy is conserved

• Inelastic collision

• Elastic collision

• Impulse

• Linear momentum

Average net external force multiplied by the time the force acts; equal to the change in momentum

• Impulse

• Momentum

• Angular momentum

• Isolated system

Collision in which objects stick together after impact and kinetic energy is not conserved

• Impulse

• Impact

• Elastic Collision

• Inelastic Collision

A system in which the net external force is zero

• Isolated system

• Law of conservation of momentum

• Ideal system

• Balanced system

The impulse, or change in momentum, is the product of the net external force and the time over which the force acts

• Change in momentum

• Angular momentum

• Law of conservation of momentum

• Impulse-momentum theorem

The product of a system's mass and velocity

• Conservation of momentum

• Angular Momentum

• Linear momentum

• Impulse-momentum theorem

An abstract point in space where the entire mass of the object has been concentrated.

• Point masses

• Center of mass

• Finite density point

• Idealized masses

The backward movement of an object caused by the transfer of momentum from another object in a collision

• Impulse

• Recoil

• Elastic collision

• Inelastic collision

When the net external force is zero, the total momentum of the system is conserved or constant

• Inelastic collision

• Elastic collision

• Impulse-momentum theorem

• Law of conservation of momentum
