3. transfer the movement of energy from ne location to another.
7. in which there is no matter or in which the pressure is so low that any particles in the space do not affect any processes being carried on there
8. wave- a wave vibrating in the direction of propagation.
9. the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
10. energy energy which a body possesses in virtue of being in
13. web a system of interlocking and indepentdent food chains
15. potential energy A form of potential energy that is stored in chemical bonds between atoms.
16. circuit a closed loop path through which electrical current can flow
18. energy a form of potential energy that is stored in chemical bonds between atoms
19. displacement, distance, velocity, acceleration, speed, and frame of reference to an observer, measuring the change in position of the body relative to that frame with a change in time.

1. transformation process where energy changes from one from to another energy transformation
2. the ability to work
4. potential energy Gravitatonal potential energy is energy an object possesses because of its position in a gravitational field
5. of conservation of energy the rule that energy cannot be created or destroyed.
6. the substance or material through which a wave propagates, or travels
11. wave-a wave that oscillates perpendicularly to the direction of the wave's advance.
12. energy A form of potential energy that is stored in chemical bonds between atoms.
14. movement back and forth at a regular speed.
17. disturbance or variation that transfers energy progressively from point to point in a medium and that may take the form of an elastic deformation or of a variation of pressure, electric or magnetic intensity, electric potential, or temperature.
