Momentun and Impluse definitions

Momentum

The product of an object’s mass and it’s velocity

Equation: p=mv

Unit of measurement: kg×m×s^-1

Linear Momentum

The vector quantity with the same direction as the velocity of the object

Newton’s Second Law in terms of Momentum

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

Fnet = /_\p / /_\t

Or

Fnet = p(final) - p(initial) / t(final) - t(initial)

Impulse

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

Unit of measurement: Newtwon Second N×s

Equation: Fnet × delta t =m × delta v

Law of Conservation of Linear Momentum

The linear momentum of an isolated system remains constant (is conserverd)

Elastic Collision

A collision in which both the momentum and kinetic energy is conserved

Inelastic Collisions

The total kinetic energy is not conserved but the total momentum is conserved
