See lessWhat is the momentum
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." ... Momentum depends upon the variables mass and velocity.
