The momentum of a body is defined as the product of its mass and velocity. Its physical symbol is 'p'.
The formula for momentum is given by
p = mv
Where,
m - the mass of the body in kg
v - velocity of the body in m/s
Therefore, the unit of momentum is expressed as the kg m/s
The momentum of a body is always associated with its motion. It is a vector quantity and it is directed in the direction of the velocity vector.
If a body is at rest, the momentum associated with the body is zero.
The momentum plays a significant role in the kinematics of the body. As similar to the energy conservation law, the total momentum of the body is conserved.
