Stopping distances
Thinking distance and braking distance, what changes each, reaction times from a ruler drop, and why braking distance goes with speed squared.
You will be able to
- Split a stopping distance into thinking and braking distance
- Measure a reaction time with a ruler drop
- Explain why doubling the speed makes the braking distance four times as long
