Deceleration and stopping distance

Deceleration and stopping distance

Stopping distance diagram showing a car moving from hazard seen to brakes applied to car stops, with thinking distance, braking distance and total stopping distance labelled

When a car slows down, its velocity changes, so it is still accelerating. If that acceleration acts opposite to the motion, we call it deceleration.

2.5 Stopping and braking distances Lesson

  1. GCSE
  2. /Physics
  3. /2.5 Stopping and braking distances

Step-by-step lessons on Edexcel GCSE Physics 2.5 Stopping and braking distances, covering 2.5.1 Stopping distance and reaction time, 2.5.2 Factors affecting stopping distance, 2.5.3 Dangers of large decelerations, and 2.5.4 Braking distance and initial speed. 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.
