front 1 energy | back 1 the ability to do work |
front 2 motion | back 2 a change in position |
front 3 kinetic energy | back 3 energy of motion |
front 4 potential energy | back 4 stored energy |
front 5 generator | back 5 a device used to convert mechanical energy to electrical energy |
front 6 Law of Conservation of Energy | back 6 energy cannot be created or destroyed |
front 7 elapsed time | back 7 the length of time that passes from one event to another |
front 8 speed | back 8 the rate at which the position of an object changes |
front 9 distance | back 9 the length of a path between two points |
front 10 force | back 10 a push or a pull |
front 11 velocity | back 11 the speed and direction in which an object is moving |
front 12 acceleration | back 12 the rate of change of velocity |
front 13 friction | back 13 a force that opposes motion and that occurs when things slide or roll over eachother |
front 14 inertia | back 14 the tendency of an object to resist changes in motion |
front 15 Newton's 1st Law of Motion | back 15 n object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force |
front 16 Newton's 2nd Law of Motion | back 16 the acceleration of an object depends on the mass of the object and the amount of force applied |
front 17 Newton's 3rd Law of Motion | back 17 for every action there is an equal and opposite reaction |
front 18 gravity | back 18 the force of attraction between any two objects that have mass |
front 19 Law of Universal Gravitation | back 19 gravitational force depends on the mass of the two objects involved and on the distance between them |
