In the context of swing motion, amplitude refers to the maximum displacement or distance reached by a swinging object from its equilibrium position. It is a measure of how far the object moves away from its rest or central position.
For example, consider a pendulum swinging back and forth. The amplitude of the swing is the maximum distance the pendulum bob moves away from its equilibrium position in either direction. If the pendulum swings to the left and right, the amplitude would be the maximum distance it reaches on either side.
Amplitude is often used to describe the size or magnitude of a swing motion. A larger amplitude indicates a more significant swing, whereas a smaller amplitude corresponds to a smaller range of motion.
In simple harmonic motion, such as that exhibited by a pendulum, the amplitude remains constant unless affected by external factors such as damping or the application of forces.
