What is the angle described at the center of the circle by a moving body along a circular path called?

• A. Angular velocity
• B. Angular momentum
• C. Angular displacement
• D. Angular frequency

Answer: (C)

The term used to describe the angle at the center of the circle by a moving body along a circular path is known as angular displacement. This concept refers to the change in the angle as the object moves around the circular path, measuring how far the object has rotated from its initial position. It is typically expressed in radians and represents the position of the body in relation to a reference line. Angular displacement is specifically focused on the amount of rotation and does not consider the time it takes for that rotation to occur. This distinguishes it from other terms like angular velocity, which relates to how fast an object rotates over time, or angular frequency, which relates to the rate of rotation as it cycles through one complete revolution. Angular momentum, on the other hand, is a measure of the rotational motion of an object, incorporating its mass and the radius of rotation alongside the velocity. Understanding angular displacement is crucial for analyzing the motion of objects in circular paths, enabling a clearer comprehension of rotational dynamics.
