| Force | a push or a pull measured in N |
| push | exert a force away from the body exerting it |
| pull | attraction or influence |
| motion | act or process of changing places |
| recieve | to support pressure or weight |
| action | the state of beingin motion |
| reaction | acts in opposite direction or action |
| reciever | one who recieves a force |
| agent | exerts a force |
| mass | the measure of the amount of matter in an object (grams or kilograms) |
| matter | anything that has weight (what makes up a substance0 |
| weight | the amount of gravitational force acting on a object |
| newton | the metric unit used to measure force |
| gram | a unit of measurment = to .001 of a kilogram |
| contact forces | an agent that touches the reciever when delivering a force |
| noncontact forces | when an agent delivers a force that doesn't touch the reciever |
| gravity | the quality of having weight |
| gravitational force | causes objects to move toward eachother (mutual force of attraction) |
| inertia | the property of matter to remain at rest or resist change in its state of motion |
| balanced forces | when 2 things push together equaly |
| unbalanced forces | when 2 forces push against eachother and one is stronger |
| friction | when to things rub against eachother and create heat |
| frictional force | the force that resists motion of objects rubbing against eachother |
| force meter | a tool used to measure muscle strength |
| strength | the force measured in numbers |
| equal arm balance | a scale used to measure and weigh objects |
| attractive force | to pull something towards the surface |
| electric force | noncontact force w/ electric charge |
| static electricity | electricity that builds up in objects by 2 things rubbing together |
