Question

SI

Answer 1

Answer:

p = mv

Explanation:

• 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.
