Forces and motion
- Acceleration is the rate of change in velocity of an object.
- The most common unit of acceleration is m/s/s which can also be written as m/s2 or ms-2. This means the rate of
change in velocity per second.
- For example if an object increased its velocity by 2 metres every second then its acceleration would be
- Acceleration = change in velocity / time taken for change.
- Therefore if an object travels from stationary to 5 m/s in 2.5 seconds then its acceleration = 5/2.5 =
- Uniform acceleration is just the name given to a constant acceleration.
