Braking Distance Explained

What determines how quickly a car can stop? How do tires and brakes affect braking distance? This video explains an equation that can be used to determine how well a car brakes. • Want to include factors such as rain or ABS no ABS? Here is how to alter the equation. In the original equation, multiply u (frictional coefficient) by acceleration, so the new equation reads: • D=0.5*V^2/(u*a) • Leave a as 1, and change u according to the condition. • With ABS ON: u can be considered 1, since ABS will attempt to maintain peak friction. • With ABS OFF: u will be less than 1, and will equal the frictional coefficient of a tire slipping on pavement. • With RAIN, and ABS ON: u will be less than 1, and will equal the frictional coefficient of a tire on wet pavement. • With RAIN, and ABS OFF: u will be less than 1 (and than with ABS ON), and will be equal to the frictional coefficient of a tire slipping on wet pavement. This is the worst case scenario of the four listed. • Please feel free to rate, comment, and subscribe! • And don't forget to check out my Facebook page: • / engineeringexplained • Also check out my official website: Make suggestions, participate in forums, enter for Car of the Month, learn through logically ordered lessons, read FAQs, and plan your future! • http://www.howdoesacarwork.com • • NEW VIDEOS EVERY WEDNESDAY!
