1) is at the top of a hill.
2) is at the bottom of a hill.
3) has not yet started moving.
4) has just left the bottom of a hill.
provide an explanation. you!

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.

Match these items. 1. coulombs __force 2. ohms __emf 3. centimeters __resistance 4. newtons __charge 5. volts __length

Give an example in which the electrical energy changes to light energy
