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.
Deriving the centripetal acceleration formula. A body that moves in a circular motion (of radius r) at constant speed (v) is always being accelerated. The acceleration is at right angles to the direction of motion (towards the center of the circle) and of magnitude v2 / r. The direction of acceleration is deduced by symmetry arguments.
