Circular motion changes velocity
Circular motion changes velocity

Speed is a scalar quantity, but velocity is speed in a stated direction. An object moving in a circle can have constant speed while its velocity changes because its direction changes continuously.
Step-by-step lessons on Edexcel GCSE Physics 2.4 Circular motion, inertia and momentum. Each one builds up to exam-style questions. Master the required practical work and core equations early, since both papers can draw on content and maths skills from across the whole specification.
