| Question | Answer |
|---|---|
| Newton'sFirst Law of Motion (The law of Inertia) | an oject at rest will stay at rest and an object in motion will stay in motion Until is acted on by and equal and opposite force |
| Newton's Second law of motion | acceleration depends on the mass of an objecr and the force pushing or pulling on the oject. (F=MxA)-(A=f divided M) |
| Newton's Third law of Motion | for every action force there is an egual and opposite reaction force.(comes in pairs) |
| acceleration | a change in speed or direction;depends on the mass of an object and the force pudhing or pulling the object. |
| average speed | describes the movement for an entire trip by dividing measured distance by measured time. |
| force | a push or pull;for example, gravity and friction; can be balanced or unbalanced and can be found mathematically by multiplying mass times acceleration. |
| friction | the push or pull that opposes motion when two sliding surfaces are sliding on eachother. |
| gravity | a pull that every object exerts on every object and that pulls all things toward earth in the same way. |
| inertia | resistance to a change in motion. |
| mass | the amount of matter in an object. |
| scientific law | a theory about the natural world that has been tested many times and produces the same results. |
| weight | measure of how much earth's gravity pulls down on an object. |
| what is being measrued on a tripple beam balance? | mass |
