An Indy car is pushed down on the track by the Bernoulli effect. Where does the air flowing around the moving car travel the fastest? a
above the car
b
under the car
c
in front of the car
d
behind the car

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
