F1 vs road car braking distance
Loading...

BMW M3 vs. BMW F1 car braking from 120 mph!
FYI: 36 m = 105 feet.
pretty impressive if you ask me.

I can even stop faster in my Smart Forfour. By hitting a tree.
-
that aint an M3!!!!!!! :P
-
bla bla bla who gives a shit
-
That is not an M3!

@TheGyldenlove I could write you an essay about this. Yes, the car stops twice the distance. That has no meaning without. You said 'Braking force'. Why would you say twice the braking force when the bmw clearly weighs 2x as much maybe more. Even with 4x as much braking force, you haven't thought about friction, reaction time etc... in short, do not come to a conclusion without thinking through the issue clearly taking into account all the factors and a little bit of intelligence will help.

@TheGyldenlove You are judging your theory based only on what you see on screen. Please don't argue with me. I am studying undergrad physics. I think I know. momentum is only useful when determing the relationship between 2 colliding objects and how one will impart some of it's momentum to the other. It is called the conservation of momentum. It has no relationship with the kinetic energy required to stop the vehicle in 'Joules' and is determined by many factors like normal reaction force etc.

@Master1906 No, it is the momentum, if you have twice the momentum you need twice the braking force to stop in the same amount of time (and since they are going the same speed, same time means same distance)
-
@ImTheSecretSquare No it isn't. It is the kinetic energy not the momentum
-
@neoc03 Well, really what's important here is the mass, not the "weight" of a car based on downforce. The F1 has half as much mass as the M3 regardless of how fast it's going, so it has half as much momentum (mass * velocity) at the same speed, and momentum is what the brakes need to overcome.

thats not an M3, M3 has the air vent on each side, thats just a normal 3-series

So.. to improve road safety.. we should all drive.. F1 cars?
