| Question | Answer |
|---|---|
| Forces that are not equal | unbalanced forces |
| a tool used to make work easier | simple machine |
| force that pulls objects in the Universe toward one another | gravity |
| measure of how hard it is to slow down or stop an object | momentum |
| change in position or place | motion |
| simple machine that moves a load around a fulcrum | lever |
| an object's speed in a particular direction | velocity |
| The point on which a lever pivots | fulcrum |
| an object with at least one slanting side ending in a edge, which cuts material apart | wedge |
| a force that opposes motion when two surfaces rub together | friction |
| a line or course along which a person or thing moves | direction |
| a push or pull that causes an object to move, stop, or change direction | force |
| simple machine that uses a slope to make work easier | inclined plane |
| forces that are equal | balanced forces |
| property of matter that keeps something moving in a straight line or at rest | inertia |
| an object's place or location | position |
| amount of matter in an object | mass |
| simple machine that uses a rope to change direction of the force | pulley |
| measure of distance an object moves in a given amount of time | speed |
| an inclined plane wrapped around a pole which holds things together or lifts materials | screw |
| simple machine that uses a rod to attach wheels | wheel and axel |
| change in motion caused by unbalanced forces or velocity | acceleration |
| energy an object has because of its place | potential energy |
| energy of motion | kinetic energy |
