By the end you’ll be able to

Distinguish between distance and displacement, and between speed and velocity, using the ideas of scalar and vector quantities.
Calculate speed from distance and time using $v=\frac{s}{t}$, and calculate distance or time by rearranging the equation.
Calculate average speed for a journey, including non-uniform motion and multi-stage journeys.

Interpret velocity–time graphs to describe motion, determine acceleration from the gradient, and determine displacement or distance travelled from the area under the graph.

Apply appropriate units, conversions and sign conventions for motion quantities, including $\text{m}$, $\text{s}$, $\text{m s}^{-1}$ and, where needed, unit conversions such as $\text{km h}^{-1}$ to $\text{m s}^{-1}$.
