Momentum = (mass) x (velocity)
(Remember that momentum is a vector ... it has a direction. Its direction is the same as the velocity.)
An increase in either mass or velocity will increase the momentum.
It's pretty hard to increase the mass of a moving object, so I think the better answer is velocity .
An increase in either mass or velocity will result in an increase in momentum of an object. This is because momentum is the product of an object's mass and its velocity ( p = mv ), making it directly proportional to both quantities. Moreover, applying a force for a certain duration, known as an impulse, will change an object's momentum. The longer the force is applied, the greater the change in momentum will be. Thus, a larger force, or applying it for a longer time, will both cause a significant change in momentum, according to the impulse-momentum theorem.
Momentum increases with an increase in either mass or velocity. Since momentum is calculated with the formula p = m × v , increasing either value will raise the momentum. However, increasing velocity is often a more common method to change momentum in practical scenarios.
