Mechanics:Momentum and Impulse

Contact forces arise from the physical contact between two objects

Non contact forces arise even if two objects do not touch each other

Liner momentum is the product of an object's mass and its velocity

The net force acting on an object is equal to the rate of change of momentum of the object in the direction of the net force

The total linear momentum in an isolated system remains constant

A system in which the net external force acting on the system is zero

The product of the resultant/net force acting on an object and the time the resultant/net force acts on the object

A collision in which both total momentum and total kinetic energy are conserved

A collision during which kinetic energy is not conserved
