Question

What is the new gravitational potential energy when the height becomes
4 h

  1.  4 space G P E
  2.  fraction numerator G P E over denominator 4 end fraction
  3.  16 space G P E
  4.  fraction numerator G P E over denominator 16 end fraction

hintHint:

If the height of a body becomes 4h, the gravitational potential energy becomes 4 GPE.

The correct answer is: 4 space G P E


    • The gravitational potential energy is due to the height of an object above the gravitational field.
    • The change in height triggers the gravitational potential energy.
    • If the height changes to 4h,
    •   G P E apostrophe equals m g h to the power of apostrophe
space space space space space space space space space space equals m g left parenthesis 4 h right parenthesis
space space space space space space space space space space equals 4 m g h
space space space space space space space space space space equals space 4 G P E
