So the higher an object is above a surface, the more potential energy it has.  Dane is dropping bouncy balls out of windows. He drops a green ball out of the first story window, then a red ball out of the second story window. The ball with the most potential energy is the red ball or green ball?
red ball

(Q).
Its harder to overcome friction between heavier objects and the floor than it is between lighter objects and the floor.  Fred was moving a desk across the room. He then pushed a chair and it was much easier. This is because the lighter chair had less or more friction with the floor?
(A).
less


Ques:The more an elastic object is stretched or compressed, the greater its elastic potential energy is.  What will happen to the amount of elastic potential energy in Jim's rubber band if he expands it more potential energy or less potential energy?

Ans:less potential energy


Question: However, the energy is diluted as an electromagnetic wave travels farther from its source because it spreads out over an ever-larger area.  Something with a lot less energy travels short distances or long distances?
Answer:
short distances
