- Velocity is speed in a particular direction, eg.
- 10 m/ph, due north
- Speed is how fast something is travelling, eg.
- 10 m/ph
Acceleration:
- How quickly the velocity/ speed is changing, eg.
- Start: 5 m/ph , End: 25 m/ph , Time Taken: 4 secs
- The velocity changes by 5 m/ph each second, so we show this by: 5 m/s
- This means that the velocity increases by 5 m/s each time
Acceleration (m/s ) = Change in velocity / time taken (s)
