Rotary Motion

Rotary motion refers to the movement of an object around a fixed axis or point, like a wheel turning on its axle. Imagine a spinning top or a door hinge—it rotates around a central line. In this motion, every part of the object moves in a circular path, and the rate of rotation is measured in degrees or radians per second. Rotary motion is fundamental in machinery and devices, translating energy into rotational movement to perform work, such as turning gears, motors, or turbines, enabling many technologies and mechanical functions.
