Three positions of a horizontal spring-mass oscillator at x=-A, x=0, and x=+A with speed and energy labels

An oscillation is repeated motion about an equilibrium position, where the resultant force is zero. The displacement xxx is the signed distance from equilibrium, while the amplitude AAA is the maximum value of ∣x∣|x|∣x∣.

Step-by-step lessons on Edexcel A Level Physics Energy in oscillations. Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks across the three papers require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
