Elastic collision Study guides, Revision notes & Summaries

Elastic Objects interact with each other without producing sound, heat, or light *Both momentum and kinetic energy are conserved, total momentum and kinetic energy before and after are the same Ex: the two magnets facing each other Inelastic Sound, heat, or light are produced, so kinetic energy is NOT conserved *Kinetic Energy is different before and after the collision, BUT momentum is conserved Completely Inelastic Two objects strike each other and stick together *Kinetic ...

Types of body damage Direct; Indirect; Minor; Major Direct Damage Results in direct contact with an object. Holes, tears, gouges, and scratches are typical. Generally 10% of collisions result in direct damage Indirect Damage Results from direct damage. Impact cause another panel to lift, buckle, or tear. Rear end collision may result in damage near middle of car Minor Damage Involves little repair time and skill to complete Major Damage Requires more: time, s...
