A moving object has kinetic energy. Kinetic energy can be converted to other 
types of energy with a transducer, and as such, will slow down the moving 
object by removing the energy from it. Suppose a car is covered with a 
piezoelectric film which is connected to a capacitor. If the car was moving at 
a hish speed and hit a tree, would the piezoelectric material absorb the 
impact (partially) by changing the energy to electricty and storing it in a
