|---|---|
| Motion | An object in motion |
| Reference Point | Is a place or object used for observation |
| Distance | Is a length of a path |
| Displacement | Is length and direction that an object has moved |
| Vector | Displacement |
| Distance | is scalar because it does not have a direction |
| Displacement | is a vector because it does have a direction identified by an arrow |
| Motion | is a change in position measured by distance and time |
| Speed | Tells us the rate at which an object moves |
| Velocity | tells the speed and direction of a moving object |
| Acceleration | tells us the rate speed or direction changes |
| Scalar | measurements that have magnitude , or size only |
| work | A word that describes what is done on an object |
| energy | The ability to do work or cause change |
| kinetic energy | Energy that an object has due to its motion |
| potential energy | Stored energy that results from the position or shape of an object |
| gravitational potential energy | Potential energy related to an object's height |
| elastic potential energy | The energy of stretched or compressed objects |
| mechanical energy | An object's combined kinetic energy and potential energy |
| Law of Conservation of Energy | The rule that energy cannot be created or destroyed |
