What is the rate of change of angular displacement of a rotating body known as?

• A. Angular velocity
• B. Centripetal force
• C. Linear velocity
• D. Acceleration

Answer: (A)

The rate of change of angular displacement of a rotating body is referred to as angular velocity. This term describes how quickly the position of an object changes over time as it rotates around a fixed axis. Angular velocity is typically measured in radians per second or degrees per second, indicating how many radians or degrees the object moves through in one second. In rotational motion, angular displacement represents the angle through which an object has rotated, and when we measure how fast this angle changes, we arrive at angular velocity. It is important in many applications, such as understanding the dynamics of gears, wheels, and various mechanical systems that involve rotation. The other options refer to different physical concepts. Centripetal force relates to the force required to keep an object moving in a circular path, linear velocity refers to the speed of a point moving along a linear path, and acceleration refers to the rate of change of linear velocity. Each of these terms serves a distinct purpose in the study of motion and is not a measure of angular displacement's rate of change.
