Force and Motion
| Term | Definition |
|---|---|
| acceleration | if speed and or direction change |
| velocity | speed in a particular direction |
| unbalanced force | causes a change in motion of something |
| balanced force | position or motion will not change- equals zero |
| kinetic energy | energy in motion |
| potential energy | energy based on objects position |
| speed | how fast something moves |
| force | push or pull |
| law of conservation of energy | energy cannot be created or destroyed, only transfrormed |
| friction | the force of resistance of two surfaces touching eachother |
| work | use if force to move an object |
| inertia | the tendency of an object at rest to stay at rest and an object in motion to stay in motion |
| Newton's 1st Law | Inertia |
| Newton's 2nd law | F=MA Force equals mass times acceleration |
| Newton's 3rd Law | For every action there is an equal and opposite reaction |
| mass | how much matter is in an object |
| weight | measure of the gravitational pull on an object |
