Harmonic motion refers to a type of periodic motion where an object oscillates back and forth over a central equilibrium point, typically described by sinusoidal functions. It is characterized by the restoring force being directly proportional to the displacement, leading to simple harmonic motion as seen in systems like pendulums and springs.

Harmonic motion

Periodic motion refers to any motion that repeats itself at regular intervals, such as the swinging of a pendulum or the oscillation of a spring. It is a fundamental concept in physics and engineering, serving as the basis for understanding behaviors in wave mechanics, acoustics, and even electrical circuits.

Sinusoidal functions, characterized by their wave-like oscillations, are fundamental in modeling periodic phenomena such as sound waves, light waves, and alternating current. They are defined by the sine and cosine functions, which exhibit properties of amplitude, frequency, phase shift, and vertical shift, allowing for versatile applications in both theoretical and practical contexts.

A restoring force is a force that acts to bring a system back to its equilibrium position. It is typically proportional to the displacement from equilibrium and is a fundamental concept in understanding oscillatory motion and stability in physical systems.

restoring force

Displacement is a vector quantity that refers to the change in position of an object, defined as the shortest path between the initial and final points in a specific direction. It is distinct from distance, which measures the total path traveled regardless of direction, making displacement crucial for understanding motion in physics.

Simple Harmonic Motion (SHM) is a type of periodic motion where an object oscillates back and forth through an equilibrium position, experiencing a restoring force proportional to its displacement. This motion is characterized by its sinusoidal wave form, constant amplitude, and constant frequency, making it fundamental to understanding various physical systems like springs and pendulums.
