Test Your Own Knowledge
Before reading the material in this chapter test your current knowledge with
the following questions:
- The path of a toy hovercraft was recorded over 10 seconds (a graph of distance against time is shown in Figure 9.1). When was the toy accelerating? At a steady speed? Decelerating?
- How do you calculate the average speed of the toy?
- The toy achieved a top speed of 2.5 m/s. Between which times did the toy achieve this higher speed?
- Sketch a chart showing speed against time for the chart in Figure 9.1.
