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