Terms | Definitions |
|---|---|
 newton | unit of force, equal to the force that causes a 1 kilogram mass to accelerate at a rate of 1 m/s² |
| balanced forces | forces that cancel each other because they are equal in strength and opposite in direction |
| unbalanced forces | forces that do not cancel each other out and result in a net force on an object |
| weight | measure of the force of gravity acting on an object |
| force | push or pull that acts on an object, causing it to move, change speed or direction, or stop moving |
| fluid friction | friction that occurs as an object moves through a fluid. Also called "drag" |
| rolling friction | friction that occurs when an object rolls over a surface |
| friction | force that opposes motion, or resistance caused when two surfaces touch or rub together |
| static friction | friction that acts on objects that are not moving |
| sliding friction | friction that occurs when one solid surface slides over another |
| gravity | force that exists between any two objects that have mass, attracting or pulling them together |
| mass | the amount of matter in an object; the amount of space an object takes up |
