Momentum is a measure of an object tendency to move in a straight line with constant speed. Momentum has a direction and can be used to predict the resulting direction of objects after they collide, as well as their speeds.
Linear momentum or translational momentum is the product of the mass and velocity of an object. If a force F is applied to a particle for a time interval Δt, the momentum of the particle changes
