Unbelievable How To Work Out Stopping Distance

If the car is travelling uphill gravitational forces acting against the motion of the car will make it stop more quickly.

How to work out stopping distance. First choose a fixed point on the road ahead. Calculate the work done in bringing a moving vehicle to rest The diagram shows some typical stopping distances for an average car in normal conditions. Stopping distance can be hard to work out when you are driving but there is one handy tip that can help you get braking right.

70 MPH 35 MPH 105ft 3 315ft stopping distance includes thinking reaction time. If you want to calculate stopping distances in metres instead of feet simply do the calculations in feet and then convert the final answer back to metres. Two Second Gap Rule.

1 foot 03048 metres or to ease calculation 1 foot is roughly equal to 310 metres ie. That is the equivalent of half a mile or the length of 8 football pitches. Procedure Firstly I will drop the lighter ball 1 and measure its stopping distance and record this result.

In an emergency the average driver takes approximately 15 seconds to react. This is simply the thinking distance added to the braking distance so at 40mph it would be 40 80 feet. With correct parameters its a perfect equation for an accurate calculation of the stopping distance of your car.

Overall Stopping Distance. To estimate stopping distance when driving remember that the average car length is 15 feet. This formula is commonly used in road design for establishing the minimum stopping sight distance required on a given road.

I will then drop the same ball another 4 times and record those results. Remembering stopping distances is easy. This could be a signpost or marker on the side of the road or.
