Question

define momentum but not in terms product of mass and velocity

Answer 1

Impulse = change in momentum.
Therefore, force * time = change in momentum

Momentum = n h/2pie *r

Answer 2

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 is a measure of the kinetic energy of the object.
