Leaving Cert Physics · Forces and Motion
Higher Level
The rate of change of displacement with respect to time, measured in m s⁻¹ and always quoted with a direction. On a displacement-time graph it is given by the slope, so a curved graph shows that it is not staying constant.
Ordinary Level
Speed given together with the direction of travel, such as 12 m s⁻¹ due north.
