What is the velocity of air in still air?

Speed of sound in still air is c ≈ 331 + 0.6 × T. T = Temperature. Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.

How to Convert Velocity?

Velocity measures the displacement of an object per unit of time. Displacement is the distance from the starting point. For example, if you were driving to an ending point 1 mile from your starting... Read More »

How to Convert MPH to Velocity?

Speed and velocity are terms that are often interchanged. They are not, however, identical. Speed is a scalar entity that describes how fast a body is moving. Velocity is a vector, so it not only i... Read More »

How to Measure Velocity?

Velocity is the rate at which an object changes position, or how quickly something moves. This is a key concept in most physics lectures; it is commonly presented to students in a word problem. Lea... Read More »
