Source sentences:
text: An elastic collision generally occurs when an elastic or hard object experiences a collision that bounces off another elastic or hard object, where the kinetic energy and momentum are the same before and after the collision.
text: In the forces between the bodies are also conservative, so that no mechanical energy is lost or gained in the collision, the total kinetic energy of the system is the same after the collision as before.
text: An elastic collision occurs when the total kinetic energy, or movement energy, of two or more objects is the same after a collision as before the collision.
text: As a result of the fundamental law of conservation of energy, which states that energy can never be destroyed, the total energy after two objects collide must be the same as it was before the collision.
