2 or dioxygen. Ozone is formed from dioxygen by the action of ultraviolet light and also atmospheric electrical discharges, and is present in low concentrations throughout the Earth's atmosphere (stratosphere). In total, ozone makes up only 6993600000000000000â 0.6 ppm of the atmosphere.
Of the many car driving tips that might be offered, this one isn't intuitive-accelerate through curves to gain better traction. It seems that acceleration on a curve would cause a vehicle to loose traction and fishtail. It does if you apply too much, but limited acceleration improves traction when taking a curve.
A tripling of the speed would increase the stopping distance by a factor of nine. And a quadrupling of the speed would increase the stopping distance by a factor of 16. The stopping distance is proportional to the square of the speed of the vehicle.This mathematical relationship between initial speed and stopping distance is depicted in the animation below. Three cars with identical braking systems are traveling three different speeds..5*m*v 2 = F*d. The above equation shows that the stopping distance (d) is proportional to the square of the speed (v 2). And that's exactly what the driver's education course taught you. And now you know: it's PHYSICS ! For more information on physical descriptions of motion, visit The Physics Classroom Tutorial.
