Newton

Law of conservation of momentum

SI unit of acceleration

An object continues to be in a state of rest or of uniform motion along a straight line unless acted upon by an unbalanced force.

The rate of change of momentum of an object is proportional to the applied unbalanced force in thedirection of the force.

To every action, there is an equal and opposite reaction and they act on two different bodies

Kg m s^-2

The sum of momenta of the two objects before collision is equal to the sum of momenta after the collision provided there is no external unbalanced force acting on them

m s*-2
