## Stopping Distance Formula

The following formula is used to calculate the stopping distance of a moving object.

D = v^2 / (2*u*g)

- Where D is the stopping distance (m)
- v is the velocity (m/s)
- u is the coefficient of friction
- g is the acceleration due to gravity (9.8 m/s^2)

## FAQ

**What is a stopping distance?**

A stopping distance is a term usually applied to cars that describes the total amount of distance to stop when a car brakes from a certain speed. The formula above assumes constant friction, which may not be the case if the car’s wheels are rolling then start to slide and vice versa.
