| Force | push or pull thats acts on an object |
| Newton | abbreviated as N |
| Net Force | the overall force acting on an object after all the forces are combined |
| net force = 0 | all forces on an object are balanced |
| unbalanced force | causes an object to accelerate |
| Friction | Force that opposes the direction of motion of an object as it slides over a surface. |
| Static Friction | acts on objects that are not moving |
| Sliding friction | force that opposes the direction of motion of an object as it slides over a surface |
| Rolling friction | acts on rolling objects |
| air resistance | fluid friction acting on an object moving through the air |
| fluid friction | opposes the motion of an object through a fluid |
| gravity | 9.8 m/s2 |
| projectile motion | initial forward velocity and gravity |
| Newton's 1st Law | Inertia |
| Newton's 2nd Law | F = m * a |
| Newton's 3rd Law | action and reaction forces |
| Momentum | product of mass and velocity |
