Rotatory motion is the common factor among the propeller of a flying helicopter, the minute hand of a watch, and the tape of a cassette recorder.
Rotatory motion is common to the propeller of a flying helicopter, the tape of a cassette recorder, and the minute hand of a watch. These examples exhibit rotational motion where the movement occurs around an axis or a center point.
Rotatory motion involves objects moving in circles or spinning on an axis. It is different from translatory and oscillatory motion. The spinning-top, balance-wheels of engines, and the turning of the earth are all examples of rotatory motion.
Understanding rotatory motion is important in physics as it helps explain the motion of objects that rotate or spin around a fixed point.
