A Video Clip that Caught My Attention

The Physics of Car Crashes
This video is about how car crashes happen; from the fuel to the actual crash.


Three Learning Points:
  1. 1 litre of petrol contains 56,000,000 joules of energy.
  2. 80% of that energy is loss as heat in the nose (front) of the car while only 20% of the energy is converted to kinetic energy.
  3. People prefer cars with short noses so as to reduce energy loss through heat loss.
