Final answer:
A ball connected to a rotating rod undergoes circular motion as it follows a circular path around the axis of rotation. Therefore, the correct answer is A) Circular motion.
Step-by-step explanation:
The ball connected by two strings to a horizontal rotating rod undergoes circular motion. Circular motion is defined as the movement of an object along the circumference of a circle or rotation along a circular path.
In this scenario, since the rod is rotating and the ball is attached to it via strings, the motion of the ball will be around the axis of the rotating rod, following a circular trajectory.
This kind of motion is seen in examples such as a merry-go-round, where the horses on the merry-go-round exhibit uniform circular motion.
Circular motion is the movement of an object along the circumference of a circle or rotation along a circular path. In this case, the ball is connected to the rotating rod, and as the rod spins, the ball moves in a circular path around the rod.
