Answer:
Momentum is a physics term; it refers to the quantity of motion that an object has. A sports team that is on the move has the momentum. If an object is in motion (on the move) then it has momentum. Momentum can be defined as "mass in motion."
Explanation:
It is expressed mathematically as p = m * v and has units of kg m/s. The principle of conservation of momentum states that in an isolated system, two objects that collide have the same combined momentum before and after the collision.
