physics term 4

1. The transfer of heat by the movement of a liquid or gas
6. energy energy carried by light e.g the sun
8. the transfer of energy through a substance from one partical to another. heat is transferred through solids and liquids in this way.
10. of potential energy a ball at the top of a hill
12. Potential Energy The energy stored in a system of magnets as a result of the exertion of a magnetic force on each other.
14. of kinetic energy a moving car
16. energy stored energy
18. of Conservation of Energy the law that states that energy cannot be created or destroyed but can be changed from one form to another
19. variable variable that is manipulated
21. potential energy Energy stored by something that can stretch or compress
22. energy relates to the displacement of molecules in a space as a function of the normal thermal motions e.g train on train tracks.
24. energy Energy caused by an object's vibrations e.g speech
25. energy the energy contained within a system that is responsible for its temperature e.g boiling water on stove.

2. design A design in which researchers manipulate an independent variable and measure a dependent variable to determine a cause-and-effect relationship
3. potential energy Energy stored by objects due to their position above Earth's surface.
4. the transfer of heat through empty space. no substance is needed.
5. energy energy of motion
7. for calculation of potential energy Ep=mgh
8. potential energy Energy stored in chemical bonds
9. variable what is measured in an experiment
11. energy the power an atom's charged particals have to casue an action or move an object. e.g lightning
13. An educated guess
15. potential energy potential energy that results from conservative Coulomb forces.
17. potential energy Energy stored in the nucleus of an atom
20. for energy effciency Efficiency=output x 100 % input
23. does G equal? 9.8 m/s^2
