| Term | Definition |
|---|---|
| Friction | The force that one surface that exerts on another when the two surfaces rub against each other. |
| Static Friction | Friction that acts on objects that are not moving. |
| Sliding Friction | Friction that occurs when one solid surface slides over another. |
| Rolling Friction | Friction that occurs when an object rolls over a surface. |
| Fluid Friction | Friction that occurs when an object moves through fluid. |
| Gravity | The force that pulls objects towards each other. |
| Mass | The measure of how much matter is in an object. |
| Weight | A measure of the force of gravity on an object. |
| Free Fall | The motion of a falling object when the only force acting on it is gravity. |
| Air Resistance | The fluid friction experienced by objects falling through the air. |
| Projectile | An object that is thrown. |
| Compression | The part of a longitudinal wave where the particles of the medium are close together. |
| Tension | Stress that stretches rock so that it becomes thinner in the middle. |
| Force | A push or pull exerted on an object. |
| Newton | A unit measure that equals the force required to accelerate 1 kilogram of mass at 1 meter per second. |
| Net Force | The overall force on an object when all the individual forces acted on it are added together. |
| Unbalanced Forces | Force that produces nonzero net force, which changes an object's motion. |
| Balanced Forces | Equal forces acting on an object in opposite directions. |
