Momentum is how we measure mass that is in motion. Any moving object will have momentum. Under the law of physics, the object’s momentum equals mass times velocity.
Momentum = Mass x Velocity
Momentum is the quantity of motion and is compounded by the quantity of the matter moved and the velocity with which it moves. Momentum is present when you walk, run, etc. If a bicycle and a car travel down the street at an equal velocity, the car will have the most momentum.
Since velocity is considered to be a vector, momentum is considered a vector as well. This means momentum has a significance of momentum and direction—the momentum direction indicated by a vector or an arrow.
So, the correct option is (A)
