The speed that an object moves through the air.
Wind is simply the movement of air. By definition, this movement has velocity (it has speed plus a direction).
An operational definition is a way of defining a physical quantity or quality in terms of an operation performed. An operational definition of wave speed is "The speed at which sound-waves in air transfer vibratory energy characterized by rate (frequency), starting position (phase), and magnitude (amplitude) of vibration."
It is called a definition.
The definition of the speed of light in a vacuum is 300,000,000 meters/sec, or 186,000 miles/sec.
Initial speed is the original, beginning speed of an object.
The word, 'air conditioner' is a noun. The definition of air conditioner is a machine that controls the humidity and temperature of the air.
The definition of atmospheric movement is the movement of air or air masses.
they are fast
Quickness, speed
Speed of light in air ~ speed of light in vavuum = 3,00 *10^8 m/s speed of sound in air ~ 330 m/s. Speed of light is faster than sound in air
Sound is a vibration, a change in presure. In air that vibration travels at about 700 mph ... it varies with temprature and presure (average) of the air. In water it's almost 4 times as fast.
