QuestionDetails: The floor of the basement of a house is 2.9 below ground level, and the floor of the attic is4.0 above ground level. If an object in the attic were brought to thebasement, the change in potential energy will be greatest relativeto which floor? The attic, the basement, the ground or allthe same? What are the respective potential energies of1.6 objects in the basement and attic, relative to groundlevel? Express your answers using twosignificant figures separated by a comma.

I am slowly getting better and I am beginningto understand the material. Thanks for all of your help.

Explanation / Answer

For all of these, PE = mgh   where h   is the change in height. PotentialEnergy changes are maximized when height is increased alot. (A) the attic (h is highest) (B) Use PE = mgh m = mass (1.6) and h = height change (from attic to ground level)and (C) from basement to ground level.
