Lesson 2.4.7

Lesson 7 — Determining Stopping Distance

Get Focused

In this lesson we will investigate the different factors that influence stopping distance and learn how to calculate the stopping distance of a decelerating vehicle.

Consider the following essential questions as you complete Lesson 7 :

  • What factors influence reaction time ?
  • What factors influence stopping distance ?
  • Why is it important to know stopping distances
