Distance, Speed, and Time

Measure distances and times to calculate speeds.
Create and use distance-time graphs to represent the motion of an object along a straight line.
Calculate the speed of an object from the gradient of its distance-time graph.
Determine the speed of an accelerating object at a specific time by drawing a tangent and measuring the gradient of a distance-time graph (Higher Tier only).
Use ratios and proportional reasoning to convert units and compute rates.
Relate changes and differences in motion to appropriate distance-time and velocity-time graphs.
Interpret lines, slopes, and enclosed areas in motion graphs.
Calculate the average speed for non-uniform motion.
Recall and apply the equation for uniform motion: $s = v t$
