It's a drag


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.
