Question

Which of the following examples describes an increase in potential energy?

Answer 1

Answer: D.  a paint can being carried up a ladder

Explanation: Potential energy is the energy possessed by an object by virtue of its height.

$P.E=m\times g\times h$

m= mass

g = acceleration due to gravity

h = height

Thus Potential energy is directly proportional to the height of the body. The greater the height, greater is the potential energy. Thus a paint can being carried up a ladder will lead to increase in potential energy as height will keep on increasing.

Answer 2

It is D, a paint can carried up a ladder.
