Students learn how to plot and interpret speed vs. time graphs. By considering the direction of the graph students understand how an acceleration and retardation correspond to a positive or negative gradient. As learning progresses displacement is measured by calculating the area under the line.
Differentiated Learning Objectives
- All students should be able to recognise a positive gradient as increasing velocity and a negative gradient as decreasing velocity.
- Most students should be able to plot a velocity – time graph and calculate the area under the line to measure displacement.
- Some students should be able to sketch a distance – time graph from a velocity time graph.
