Question

which situation describes the best example of rotational motion?
electrons travel around the nucleus of the atom.
the runner circled the track in record time to win the track meet
the wheel spins as long as the hamster keeps running.
the tornado left a two - mile path of destruction.

Explanation:

Rotational motion is the movement of an object around an axis. The wheel spinning around its axis is a clear example of rotational motion. Electrons traveling around the nucleus is more related to atomic structure (not the typical rotational motion in the context of macroscopic objects). The runner circling the track is translational motion (moving along a circular path but the whole body is in linear - like motion around the track). The tornado's path is more about its translational movement over a distance rather than rotational motion of a single object around an axis.

Answer:

The wheel spins as long as the hamster keeps running.
