5. Which image in the collage to the right is an
example of an object not doing work?
O A. climbing a rock wall
B. a water wheel in a dry river
C. kicking a soccer ball
D. carrying a bicycle down the stairs

Work is said to be done when a force moves a body or an object through a certain distance in the direction of the force. Thus for work to be done, force and distance are required.

i.e Work done = Force x distance

It is measured in Joules.

Also, the work done by an object could be a measured of potential energy.

So that,

Work done = potential energy = mass x gravitational force x height

Considering the collage in the question, since the water wheel is in a dry river no work is done. Water wheel is a device that functions through the flow of water body, thus causing its rotation.
