☛ Momentum is defined as quantity of motion contained in a body.
☛In other words it is also defined as product of mass and Velocity.
- Momentum is represent by P.
- It is a vector quantity.
- Direction of momentum is along the direction of velocity.
- SI unit of momentum is Kg m/s.
- CGS unit of momentum is g cm/s.
- P = mv
➤ Law of conservation of momentum :-
☛ According to law of conservation of momentum,total momentum of a system or object remains constant if no external unbalanced force acts on the system or object.
☛ In other words ,If net force acting on a body is zero then momentum of the body or system before collision is equal to momentum of the body in collision.
