Braking Distance Calculator ek stop ko un hi do parts mein baantta hai jo har driving manual describe karta hai. Reaction time ke dauraan car bilkul slow nahin hoti — 100 km/h par pedal tak paanv pahunchne se pehle hi aap kareeb 42 metre chal chuke hote hain. Tabhi braking distance start hoti hai, jo physics formula v²/2a follow karti hai: ye speed ke square se badhti hai, isliye speed double karne se braking hissa lagbhag chaugna ho jaata hai. Available deceleration tyre-road friction se aati hai — dry asphalt packed snow se kareeb chaar guna better grip karta hai — aur ek downhill grade uska kuch hissa chupke se chura leti hai.
Features
Thinking, braking aur total distance alag-alag
Dry asphalt se ice tak paanch surfaces, har ek ka friction value
Adjustable reaction time — 1.5 s typical hai
Road grade input: downhill stop ko lamba karta hai
km/h with metres ya mph with feet
Car-length equivalent aur stop hone tak ka time
Braking Distance Calculator kaise use karein
Speed enter karein aur km/h ya mph chunein
Road condition select karein
Zarurat ho toh reaction time aur slope adjust karein
Thinking, braking aur total stopping distance padhein
Example
Input
100 km/h · wet asphalt · 1.5 s reaction
Output
Thinking 42 m + braking 79 m = 121 m ≈ 27 car lengths
Dry asphalt par wahi stop 91 m leta hai — baarish teen metre add karti hai.
Common errors aur troubleshooting
Result road-code table se kaafi lamba lagta hai. — Official tables aksar shorter reaction time aur ideal brakes assume karti hain. 1.0 s aur dry asphalt set karein toh classic figures reproduce ho jaayenge, phir reality ke liye 1.5 s wapas rakhein.
Speed double karne par distance double se zyada ho jaati hai. — Ye physics hai, bug nahin. Braking distance speed ke square se scale karti hai: 120 km/h ko 60 ki tulna mein chaar guna braking length chahiye.
Tool ice par steep downhill accept nahin karta. — Jab slope ke saath gravity available grip se zyada ho jaaye, wheels net deceleration nahin de paate aur stopping distance exist hi nahin karti. Ye refusal hi honest jawaab hai.
Thinking distance brakes act karne se pehle cover hoti hai — car abhi bhi full speed par hoti hai. Braking distance pads pakadne se start hoti hai aur speed ke square ko available deceleration se divide karke depend karti hai. Total stopping distance dono ka sum hai.
Braking distance speed ke square se kyun badhti hai?
Kinetic energy speed ke square se badhti hai, aur brakes usse grip-limited rate par hi kharch kar paate hain. Double speed matlab four times energy, isliye four times distance.
Baarish ya snow mein stopping distance kitna badh jaata hai?
Wet asphalt friction ko 0.8 se 0.5 tak kam kar deta hai, jisse braking phase kareeb 60% lamba ho jaata hai. Packed snow ise chaugna aur ice aath guna kar deti hai.
Kaunsa reaction time use karein?
Unexpected hazard par ek alert driver ke liye 1.5 second common planning value hai. Thakaan, distraction ya night driving ise do second se upar le jaate hain.
