Explanation:
Momentum is the measurable quantity as the object is moving and has mass and so it has the momentum. Momentum is defined as the mass (m) times the velocity (v). If an object is steady so its velocity is zero resulting in zero momentum.

Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton's second law of motion states that the time rate of change of momentum is equal to the force acting on the particle. ... Conversely, the momentum of a particle is a measure of the time required for a constant force to bring it to rest.
