| Weight | mass x Gravitational field strength |
| Gravitational Potential Energy | weight x height |
| Speed | distance / time |
| Acceleration | change in speed / time |
| Energy Transfer | power x time |
| acceleration without time | final speed squared - initial speed squared= 2 x acceleration x distance |
