Stopping Distances and Road Safety — Interactive Lesson (Ages 14–16)

A child runs into the road. How far does the car travel before it stops — and what makes that distance longer? This 21-slide interactive lesson on stopping distance takes pupils from first ideas to exam-style explanations, with 13 self-marking activities and nothing to prepare beforehand.

Teaching Stopping Distances and Road Safety in GCSE Physics

Pupils learn that stopping distance is thinking distance plus braking distance, sort factors that affect each, and calculate thinking distance from speed and reaction time. They explain why phones, tiredness and alcohol increase thinking distance, why wet roads and worn tyres increase braking distance, and how braking transfers kinetic energy to the thermal store of the brakes.

What Pupils Will Learn

• State that stopping distance = thinking distance + braking distance.
• Describe factors that affect thinking distance and reaction time.
• Describe factors that affect braking distance.
• Calculate thinking distance from speed and reaction time.
• Explain the energy transfers during braking and the dangers of large decelerations.
