Friction

What this topic asks you to be able to do

  • Describe friction as a force that can resist motion and can cause heating
  • Understand how objects move under an unchanging weight or driving force, both with and without drag, including air resistance or resistance in a liquid
  • Account for how an object comes to reach terminal velocity
  • Define, for a vehicle in motion, its thinking distance, its braking distance and its stopping distance
  • Explain the ways in which thinking distance and braking distance can be altered by a range of factors, including speed, tiredness, alcohol, drugs, load, tyre surface and road conditions
