Speed
- The speed of an object is defined as
Distance travelled per unit time
- Speed is a scalar quantity
- This is because it only contains a magnitude (without a direction)
- For objects that are moving at a constant speed, the equation for calculating speed is:
- Where:
- = speed, measured in metres per second (m/s)
- = distance travelled, measured in metres (m)
- = time, measured in seconds (s)
