| Term | Definition |
|---|---|
| Linear Motion | The movement of a body along a straight or curved path where all body parts move in the same direction as the same speed |
| Distance | Measures the path travelled from start to finish, regardless of direction |
| Displacement | A change of position, how far it is from the initial position to the final position |
| Speed (linear) | Ratio of the distance covered to the time taken |
| Speed equation | Distance / Time |
| Velocity (linear) | Ratio of displacement, or change in position, to the time taken |
| Velocity equation | Displacement / Time |
| Acceleration (linear) | Refers to a change in velocity in a given period of time |
| Acceleration equation | Change in velocity / change in time |
| Speed (Angular) | Angular distance covered divided by the time taken to complete motion |
| Velocity (Angular) | Rate of change of the angular displacement of a body over time |
| Acceleration (Angular) | Rate of change of angular velocity, or how quickly a body changes its angular position, can be positive negative or zero. |
| Projectile motion | Looks at the factors that influence the flight path of the projectile |
| Angle of release | The angle at which an object is projected into the air |
| Speed of release | The speed at which an object is thrown, kicked or propelled into the air is referred to as speed of release |
| Height of release | Difference between the height that a projectile is released from and the height at which it lands or stops |
| Torque | Tendency of an object to rotate |
