The linear momentum of a system only changes if there is net external force acting on the system. In all other instances, the total linear momentum is conserved. Collisions between the elements of a system don’t change the total linear momentum of the system. Equations 2 and 3 define impulse. To change the motion of an object requires the application of net external force according Newton’s law of motion. Combining the above-mentioned concepts produces the Impulse-Momentum theorem that can be seen in Equation 4. It states that the amount of momentum change of an object in time interval t equals to the impulse of the net external force acting on the object during the interval.There are three types of collisions: fully elastic, inelastic collision, and completely inelastic collision. Fully elastic collisions are where both momentum and kinetic energy are conserved. Inelastic collisions are those where momentum is conserved. Completely
