| Question | Answer |
|---|---|
| simple machines | simple machines make work easier |
| mass | the amount of matter that makes up an object. The lighter an object, the less force you must apply to get it in motion |
| force | a push or a pull. The more force applied the more energy is released |
| friction | a force that causes two objects in motion to speed up or slow down when they rub together. The more friction present the more an object in motion slows down |
| speed | a measure of how far an object moves in a certain amount of time |
| motion | a movement, or a change in an objects position |
| position | the place where the object is located |
| gravity | a force that pulls things toward Earth |
| the more ____ something has the more force is required to move it | mass |
| ______ make things _____ up, slow down or change directions without a force | forces speed |
| _______ vs. air resistance | gravity |
| a pull vs. ________ | friction |
| ____ vs. push | push |
| the more _____ that is applied the farter it will go | force |
| magnetic force pushes and _____ gravity Air resistance ________ | pulls friction |
| ________ opposes motion between two touching objects | friction |
| _______ pulls everything toward Earth the more ____ something has the more gravity acts on it | gravity mass |
| __________ ______ happen when one side has greater force in one direction | unbalanced forces |
| ________ ______ are two equal forces acting in opposite directions | balanced forces |
