ie, is your speed still increasing because the momentum of the vehicle is causing the car to accelerate, even for a split second, after you have stopped sending power throgh the transmission?
theory and practical seem to show 2 different things
the theory is that with no power you wouldn't accelerate any more, although you may be able to coast at that sort of speed for some distance before the speed starts to drop off
but the practical seems to be that the speedo tends to keep going after you've lifted, so does this mean the speedo needle is continuing to move after you've stopped accelerating?
i'm still confused
i can understand it the other way, as soon as you take your foot of the brake pedal, you don't slow down as quickly, but is it the opposite the other way around like it should be?
No, as soon as you disengage the clutch, your acceleration assumes a negative value and your speed begins to fall
momentum maintains speed, it does not raise it. All it affects is the rate of loos of speed due to resistive effects
The speedo is a big pile of wank and not to be believed, neither incidentally is gps, as it has a slo refresh rate and relies on doing the same thing for a period of time for accuracy.
Did no one else do o level physics?
