Key Info
  • Can a rally car beat a bobsleigh - on ice?
  • Duration: 07:28
  • Presenter Richard Hammond joins a bobsleigh team as they race along a 2km course of ice. Racing them on a road of the same distance is James May in a specially adapted car driven by a rally driver. The distance is given in metres and kilometres and timings are given so pupils can calculate average speeds. The driver memorises the course so there is an opportunity to look at angles. The commentary describes the G-force of the bobsleigh and the effect on the riders, while James hopes the extra power of the car will help beat the bobsleigh which relies on gravity alone.

Ideas for use in class
  • Pupils can look at speed and convert metres to kilometres. They can compare the two routes and calculate the average speed for each vehicle, there is the opportunity to convert between metric and imperial measures. The bobsleigh driver rotates through the corners and shows his moves so angle work is possible here. If the diameter of the tyre were known or estimated pupils can calculate where the spikes may go in the car tyres.
