Momentum, Impulse, and Collisions Terminology

Mass in motion (mass x velocity)

• Momentum

• Impulse

• Force

• Acceleration

A change in momentum (Force x time)

• Momentum

• Impulse

• Velocity

• Acceleration

The momentum of an object can be changed through the application of a force for a period of time. This change in momentum is equal to the product of the force and time. (Force x Time = Mass x Velocity)

• Impulse-Momentum Theorem

• Conservation of Momentum Theorem

• Collision Theorem

• Pythagorean Theorem

A situation in which two objects in close contact exchange energy and momentum.

• Conservation

• Force

• Impulse

• Collision

A collision in which the objects involved move separately from one another after the impact.

• Elastic Collision

• Inelastic Collision

• Impulse Collision

• Reactionary Collision

A collision in which the objects involved move together after the impact.

• Elastic Collision

• Inelastic Collision

• Impulse Collision

• Reactionary Collision

In an isolated system, the total momentum of the objects before a collision is equal to the total momentum of the objects after a collision. Any energy and momentum lost by one will be gained by another. Momentum cannot be lost or destroyed.

• Conservation of Mass

• Conservation of Energy

• Conservation of Momentum

• Conservation of Impulse

The rate of motion of an object in a given direction; the change in displacement over time.

• velocity

• acceleration

• force

• resultant

The rate of change in velocity, the change in velocity over time

• velocity

• acceleration

• force

• resultant

A vector quantity that is equivalent to the combined effect of two or more component vectors acting at the same point.

• velocity

• acceleration

• force

• resultant
