What is the difference between Air speed and Ground speed?

In general, there are two different types of speed when talking about airplanes: airspeed and groundspeed.
Ground speed is the speed of airplane relative to the Earth’s surface while airspeed – at least true airspeed – is its speed relative to the air it is flying in.

The relationship between airspeed and groundspeed is quite simple. The sum of airspeed and wind speed is groundspeed.
If the aircraft flies in the direction of the wind, it experiences tailwind, and its ground speed is higher than its airspeed. On the other hand, if the wind blows against the direction the aircraft flies in, the aircraft experiences headwind, and its ground speed is lower than its airspeed.
