- mean speed = distance travelled / time taken.
- metres per second = m/s
- kilometres per hour = km/h
- Forces
- Balanced forces are forces which are the same size
- Unbalanced forces are forces which change speed/shape/direction
- Air resistance
- can be reduced by giving it a smooth streamlined shape ( spoiler )
- terminal velocity
- the max. speed of an object
- mean speed
- aceleration
- air resistance
- friction
- drag
