| Force that opposes motion between two surfaces | Friction |
| How much matter an object has | Mass |
| The force between 2 objects (mass & distance) | Gravitational Force |
| Change of Direction | Motion |
| Describes magnitude & Distance | Scalar |
| Descibes Magnitude& Direction | Vector |
| Rate of change in position | Speed (m/s) |
| Average speed equation | s = D / T |
| Speed in a certain direction | Velocity |
| Rate in change of velocity | Acceleration |
| Combination of all forces | Net Force |
| Tendency of an object to resist changes in its state of motion | Inertia |
| A net force that causes movement | Unbalanced Force |
| When Earths gravity acts on a falling object | Free Fall |
| How much force (gravity) acts on an object | Weight (mass X gravity) |
| Mass in motion | Momentum (mass X velocity) |
