All moving objects have..
Power
Kinetic Energy
Speed
KE = ½ mv2 calculates..
The Kinetic Energy
The change in Kinetic Energy
The loss of Kinetic Energy
Since kinetic energy is proportional to the speed squared, braking distances for vehicles are also proportional to the speed squared.
When a car stops, its kinetic energy changed into:
heat in the brakes
heat in the tyres
sound of the tyres dragging
friction
magnetic force
Work Done by brakes =
loss in kinetic energy
gain in kinetic energy
difference in kinetic energy
braking force x braking distance = loss in kinetic energy
What products do petrol and diesel make?
Sulfur dioxide
