Example Of Classical Physics #2

The lateral g force you feel while driving a car around a curve is the result of the centripetal acceleration ac, which depends on two things: the speed of the car and the radius of the curve. The greater the car's speed around the curve, the greater the acceleration, as you'd guess, but ac goes up faster than the speed — it goes up with the square of the speed. The formula for ac isformula a(c = v^2/r.
That means increasing your speed in a curve by only 41% effectively doubles ac and the corresponding lateral g force.
