Matching Pairs DynamicsOnline version reinforce the difference between inelastic and perfectly elastic collisions by Muhammad Kashif Jamal - 44214/Coordinator/BSSK 1 Newton’s first law of motion: 2 Kinetic energy is conserved in a perfectly elastic collision; 3 In all interactions or collisions, 4 Newton’s third law of motion: 5 Newton’s second law of motion: 6 In an inelastic collision, kinetic energy is not conserved. relative speed is unchanged in a perfectly elastic collision. When two bodies interact, the forces they exert on each other are equal and opposite. The resultant force acting on a body is equal to the rate of change of its momentum. An object will remain at rest or keep travelling at constant velocity unless it is acted on by a resultant force. It is transferred into other forms of energy (such as heat or sound). Most collisions are inelastic. momentum and total energy are conserved.
