This is where energy goes when it is lost in a collision.
What is sound, heat or light?
200
A frictionless roller coaster that starts at height 4h will be traveling this much faster than one that starts at height h.
What is twice?
300
If the force and displacement do not have a component in this direction then no work is done.
What is parallel?
400
This quantity is found by taking the integral of Force with respect to time (the area under a force versus time graph) and is equal to the change in momentum.
What is Impulse (J)?
500
This quantity is not conserved in an inelastic collision.
