Question

Below are five descriptions of the kinetic and potential energy of objects. Which is a description of potential energy? water moving a waterwheel a skateboarder at the top of a halfpipe III. the blades of a fan turning IV. hot water molecules moving rapidly in a cup of tea V. a parachutist ready to jump out of a plane Select one: O a. I, III, and IV O b. II, III, and V O c. All of the above O d. ll and V O e. I only

Answer 1

Potential energy is energy of a subject or substance due to it's position

For example the second option says

A skateboarder at the top of hill

He has energy due to its position when he starts to move downheal his potential energy will start to convert into kinetic energy

The only other statement among the option which shows this kind of energy is

Last option

The parachutist ready to jump of the plain

So the correct option is

d. II and IV
