| Term | Definition |

| force summation | the sum of all forces generated in the body |
| centre of gravity | point at which all parts of the body are in balance |
| base of support | the area on the ground defined by the athletes contact with it |
| projectile | any object released into the air |
| newtons first law | an object will remain at rest unless acted on by some external force |
| newtons second law | when a force is applied to a mass, the result is acceleration of that mass in the direction that the force is applied |
| newtons third law | for every action there is an equal and opposite direction |
| linear motion | when all parts of a body move in straight, parallel lines |
| angular motion | rotation around an axis that can be internal or external |
| general motion | combination of linear and angular motion |
| angle of release | optimum release is 45 degrees |
| speed of release | how quickly a projectile is released |
| height of release | how high a projectile is released |
| gravity | acts on the vertical component of the trajectory of a projectile |
| air resistance | acts on the horizontal component of the trajectory of a projectile |
| biomechanics | the study of the principles of physics applied to human motion |
| force | A push or pull. It gives energy to an object. can cause a change in motion. |
| mass | a measure of the amount of matter in an object |
| acceleration | a rate of change of velocity |
| velocity | The distance an object travels per unit of time in a given direction; V = D/T |
