Final answer:
The best example of rotational motion among the provided options is the spinning hamster wheel. Rotational motion refers to an object's circular movement around an axis, such as how the Earth spins on its axis.
Step-by-step explanation:
The best example of rotational motion from the given situations is c) The wheel spins as long as the hamster keeps running. Rotational motion is the circular motion of an object around an axis of rotation. Spin is a type of rotational motion where an object rotates around an axis that passes through the center of mass of the object. In the case of the hamster wheel, as the hamster runs, the wheel rotates around its central axis, which is a clear example of rotational motion.
Other examples of rotational motion include the Earth spinning on its own axis, the blades of a ceiling fan turning, a top spinning on its axis, and an artificial satellite orbiting the Earth. Tornadoes also exhibit rotational motion; as the radius of rotation narrows, their angular velocity increases due to conservation of angular momentum.
We distinguish between spin and circular motion which at times can occur simultaneously, as in the case of the Earth rotating on its axis while also revolving around the Sun.
