The amount of energy you start out with is the amount of energy that you end up with. Only the forms of energy change. Ex. You flip on a light switch in your home and the lights g ...

Mechanical Energy: Conservation of energy
... Law of Conservation of Mechanical Energy: The total amount of mechanical energy in a closed system remains constant. This means that potential energy can become kinetic energy, or vice versa, but energy cannot 'disappear'. The mechanical energy of an object moving in the Earth's gravitational eld ( ...

... At some instant, the sphere S emits a flash of light. At a later time, the light from a point P forms a sphere F around P, and the envelopes S1 and S2 form the ingoing and outgoing wavefronts respectively. If the areas of both S1 and S2 are less than of S, then S is a closed trapped surface. ...
