Physics and Your Car
This demonstration is designed to teach you a little about cars and how friction and speed affect driving and crashing.
Calculate the “high” velocity.
Calculate the “low” velocity.
Why are the measurements done several times and averaged?
How are speed and stopping distance related?
At low speed, stopping distance is _________ cm.
Predict the stopping distance at high speed from the low speed and low speed stopping distance.
At high speed, stopping distance is _________ cm.
A 1000 kg car decelerates at a rate of 10 m/s2. What is the magnitude of the force acting on the car? Where does this force come from?
The friction between your car’s tires and the road is called ____________________.
Water and motor oil have low coefficients of friction. What does this tell us about stopping distance and road conditions/weather?
What happened if a driver applied the breaks too hard for the road conditions before the invention of anti-lock breaks?
How does the car stop? What forces are involved?
