key term - Conservation of Linear Momentum and Collisions

Definition

The conservation of linear momentum states that the total momentum of a system remains constant if no external forces act on it. In collisions, momentum is transferred between objects but the total momentum before and after the collision is always the same.

Related terms

Elastic Collision:

A type of collision where kinetic energy is conserved. After colliding, objects bounce off each other without any deformation.

Inelastic Collision:

A type of collision where kinetic energy is not conserved. Objects stick together or deform upon colliding.

Impulse:

The change in momentum experienced by an object when a force acts upon it for a certain amount of time.
