Speed
If a car travels twice as fast, it will skid four times farther because kinetic energy increases with the square of speed. If the car travels three times as fast, it will skid nine times farther compared to its initial speed.
The term for how fast moving air travels is "wind speed." It is typically measured in units such as miles per hour (mph) or kilometers per hour (kph).

Sound travels fast because it propagates through a medium, such as air, by causing particles in the medium to vibrate and transfer energy. The speed at which sound travels depends on the density and elasticity of the medium - the denser and more elastic the medium, the faster sound can travel through it. In air at room temperature, sound travels at around 343 meters per second.
