Measuring Speed (Simulation)

Students use this resource consisting of a webpage with diagrams of three cars that students can vary the speed at which they are travelling. They can calculate the time to travel 3000m and then observe the cars as they travel the distance. This demonstrates how to work out the speed of a moving object and how to make calculations ...
