A body continues to be in a state of rest or of uniform motion in a straight line unless it is acted upon by a net external force
The rate of change of momentum of a body is directly proportional to the net force acting on the body
To every action, there is an equal and opposite reaction
The product of mass m of a body and its velocity v
16. Linear momentum p is defined as
A body continues to be in a state of rest or of uniform motion in a straight line unless it is acted upon by a net external force
