Final answer:
Potential Energy is energy due to position or state, while Kinetic Energy is due to motion. For the items, a moving car and wind have Kinetic Energy, whereas a stretched rubber band and a book on a shelf have Potential Energy. The larger or faster an object, the more Kinetic Energy it has.
Step-by-step explanation:
The task involves categorizing items based on their energy type - Potential Energy or Kinetic Energy. Let's define these terms:
Kinetic energy is the energy an object possesses due to its motion.
Potential energy is the stored energy an object has because of its position or state.
Now, let's categorize the provided items:
a) A moving car - has Kinetic Energy because it's in motion.
b) A stretched rubber band - contains Potential Energy due to its elastic position.
c) A book on a shelf - has Potential Energy because of its position in a gravitational field.
d) Wind blowing through a turbine - the wind has Kinetic Energy, which is being used to turn the turbine.
For comparative kinetic energy problems:
An object with greater mass or speed has more kinetic energy.
A 200 lb. man running at 6 mph has less kinetic energy than the same man running at 7 mph.
The 2500 kg truck has more kinetic energy than the 1500 kg car if both travel at the same speed, and the truck likely uses more fuel for the same distance.
