WebThe braking force of an eddy current brake is exactly proportional to the velocity V, so it acts similar to viscous friction in a liquid. The braking force decreases as the velocity decreases. WebBraking distance ç 11 This tells us that the rate of decrease of v with respect to x is inversely proportional to the speed v. That is, Rate of decrease of speed with respect to distance / 1 Speed. Brakingfrom100km/h When talking about braking in everyday life, we talk about speed measured in kilometres per hour and distance travelled in metres.
