10.MA4Force&Energy
| Term | Definition |
|---|---|
| energy | ability to do work or cause change |
| joule | SI unit for energy (and work) |
| transformation | change |
| kinetic energy | energy of motion (part of mechanical energy) KE + PE = mechanical |
| potential energy | energy of position (part of mechanical energy) KE + PE = mechanical |
| gravitational potential energy | same as Potential Energy- just referenced to its position above the earth; higher up it is, the more gravitational potential energy it has |
| law of conservation of energy | energy cannot be created nor destroyed; only changed or transformed into another form |
| reference point | place or object you are comparing motion to |
| motion | going from one point or position to another |
| magnitude | strength |
| vector | direction |
| speed | the rate at which motion occurs- distance compared to time; d/t |
| velocity | speed with direction |
| acceleration | rate at which velocity changes; compares starting and ending velocity divided by time |
