| Question | Answer |
| an object's change in position relative to a reference point | motion |
| an object/point used to identify the motion of another object | reference point |
| the distance traveled divided by the time interval during which the motion occurred | speed |
| the speed of an object in a particular direction | velocity |
| the rate at which velocity changes over time; an object accelerates if its speed, direction, or both change | acceleration |
| acceleration in a circular motion | centripetal acceleration |
| a push or pull on an object that can affect/change its speed/direction | force |
| SI unit for measuring force | Newton (N) |
| combination of all forces on an object | net force |
| forces which do not result in motion of an object | balanced forces |
| forces which affect an object | unbalanced forces |
| the force caused by two surfaces in contact; this force opposes motion | friction |
| friction with two object sliding against each other | sliding kinetic friction |
| friction with wheels | rolling kinetic friction |
| friction with moving objects | kinetic friction |
| friction that involves an object not moving even when force is applied to it | static friction |
| the force that attracts an object to another more massive object | gravity |
| a substance wich opposes friction | lubricant |
| the law made by Isaac Newton that states the concepts of gravity | law of universal gravitation |
| measure of gravitational force on an object | weight |
| amount of matter in an object | mass |
| What peanuts really are | aliens from planet Jupiter |
