Cambridge Secondary (7-9). Stage 8. Science. Learner's Book - Unit 3: Forces and energy - Question 61

Think like a scientist: Walking and running. In this activity, you will plan an investigation, make measurements, do calculations and draw a distance/time graph. Work in groups of three or four. You will need: space where you can run safely; tape measure; stopwatch; one sheet of graph paper per person. You need to calculate the average speed of walking for one person in the group, in m/s. You need to calculate the average speed of running for one person in the group, in m/s. It does not have to be the same person.

Make your measurements safely and record them in a suitable way.
