It's a drag

TLF ID L51

Investigate the braking efficiency of cars and trucks. Test stopping distances under controlled conditions. Compare effects of vehicle type, tyres, road surface and weather conditions. Choose driving speed, then apply brakes and compare stopping distances. Answer questions about friction, tyres and driver fatigue. This learning object is one in a series of two learning objects.



Educational details

Key learning objectives
  • Students relate braking distance to driving speed, vehicle mass, tyres and road conditions.
  • Students demonstrate that reaction time contributes to total stopping distance.
Educational value
  • Simulates a vehicle driving along a road with interactive controls for type of vehicle, speed, type of tyres, road surface and weather.
  • Allows students to start the vehicle moving then respond to a signal to apply brakes so that reaction time is recorded.
  • Shows that stopping time is a combination of reaction time and braking distance.
  • Enables students to explore the variables that affect braking distance and stopping time.
  • Provides a sample results table to print out.
  • Provides a glossary and topics for further research.
