Question
Which of the following is an example of angular motion?Question 11Answera.The path of a baseball while it is in the airb.A parachutist in free fallc.None of the answers are correctd.The arm of a pitcher throwing a ball
Solution
The correct answer is d. The arm of a pitcher throwing a ball.
This is an example of angular motion because the arm of the pitcher moves in a circular path around a fixed point (the shoulder joint). Angular motion is defined as the motion of a body about a fixed point or fixed axis. It is also called rotational motion.
In contrast, the path of a baseball while it is in the air (option a) and a parachutist in free fall (option b) are examples of linear motion, not angular motion. Linear motion is movement in a straight line.
Option c is incorrect because there is a correct answer among the options given.
