Inelastic Collisions: Inelastic collisions are collisions between objects where kinetic energy is not conserved. Some of the initial kinetic energy is transformed into other forms of energy, such as heat or sound.
Conservation of Momentum: Conservation of momentum states that the total momentum of a system remains constant if no external forces act on it. This principle applies to both elastic and inelastic collisions.
Impulse:Impulse is defined as the change in momentum experienced by an object when a force acts upon it for a certain amount of time. It can be calculated by multiplying force and time.
