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.

2.2 Speed, velocity and acceleration Lesson

  1. GCSE
  2. /Physics
  3. /2.2 Speed, velocity and acceleration

Step-by-step lessons on Edexcel GCSE Physics 2.2 Speed, velocity and acceleration, covering 2.2.1 Speed and distance–time graphs, 2.2.2 Acceleration and the uniform-acceleration equation, 2.2.3 Velocity–time graphs, and 2.2.4 Measuring speed, typical speeds and free-fall 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.
