Scalars, vectors, and motion
Scalars, vectors, and motion
A scalar has magnitude only, while a vector has magnitude and direction. Distance and speed are scalars; displacement, velocity, and acceleration are vectors, and velocity is speed in a stated direction.
Step-by-step lessons on Edexcel GCSE Physics 2.2 Speed, velocity and acceleration. 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.
