Which of these is exhibiting kinetic energy?

A. a space station orbiting Earth the high-energy phosphate bonds of a molecule of ATP

B. a rock on a mountain ledge an archer with a flexed bow

C. a person sitting on a couch while watching TV

A. a space station orbiting Earth

Explanation:

As we know that kinetic energy given as

K. E.=1/2 m v²

Where m = mass

v = velocity

If the velocity of the object is zero then it posses zero kinetic energy.

We also know that when object at a height from the ground or from a reference line then it posses potential energy and it does not have kinetic energy because object is in rest position.

In the option B and C system is in rest position that is why these type of system posses zero kinetic energy.

So the answer is A.

A. a space station orbiting Earth
