Oscillation - GCSE Physics Definition

Oscillation refers to a repeating back-and-forth motion around a central point or position, like a pendulum swinging or a guitar string vibrating. In physics, oscillations are important because they help us understand how waves work, such as sound waves or light waves. When something oscillates, it moves in a regular rhythm, spending an equal amount of time on either side of its central resting position. Oscillations can also vary in speed and size and can be found in many different systems, including springs, circuits, and even the Earth’s climate. They are a fundamental part of how we study and describe motion and energy.
