| Term | Definition |
|---|---|

| newton | the SI unit of force |
| net force | the sum total of all forces acting on an object |
| balanced forces | equal and opposite forces acting on the same object |
| equilibrium | the state in which all forces acting on an object are balanced |
| unbalanced forces | opposite forces acting on the same object that are not equal in magnitude |
| acceleration | the speeding up, slowing down, or change in direction of an object |
| friction force | a force in the opposite direction of the applied force, which opposes the motion (examples include static, sliding, rolling, and viscous) |
| applied force | a pushing or pulling contact force exerted on an object or person by another object or person |
| contact force | any force on one object by another object that is touching it |
| inertia | the property of matter that describes an object’s resistance to change in motion |
| force pair | equal and opposite forces acting on two different interacting objects |
