 Deutsche Version  Conversion of speed or velocity  units

Definition: speed (velocity) = path / time; v = d / t; d = distance, t = time
The SI unit of speed is meter per second (m/s). Another unit is kilometer per hour

Fill in the appropriate line the known velocity (speed) value

Attention: Do not re-enter the exact number of an answer.

There are really no kmh. Correct is kilometer per hour, that is km / h.

Speed of sound and acoustic velocity

 Speed is the rate of change of distance with time. Velocity is a measure of both speed and direction of a moving object. Velocity is the rate of change of displacement with time. Speed is a distance an object goes, velocity is measurment of speed AND direction.

 In a given ideal gas the sound speed depends only on its temperature. The speed of sound in still air at 0 degrees Celsius is 331.3 m/s. It depends on the temperature, and the material. Since sound is more easily transmitted between close molecules, it travels faster in the denser substance. Thus the speed of sound increases with the stiffness of the material.

 In conventional use and in scientific literature sound velocity is the same asspeed of sound or acoustic velocity. Sound velocity c should not be confused with sound particle velocity v, which is the velocity of the individual particles.
