Airspeed is speed with respect to the air, i.e. speed through the air.
Groundspeed is speed with respect to the ground, i.e. speed over the ground.
It's the vector sum of airspeed and windspeed.

What is the difference between speed over ground and speed over water?
Air speed is the speed through the air (surprise!) and the air is often moving, you can have a strong tailwind or headwind so that will affect your speed over the ground (groundspeed). The speed through the air might be 500mph, and the groundspeed either 550mph or 450mph, if the wind is at 50mph.
True or false the difference between water freezing and water boiling in the Fahrenheit scale is 100?
False because the difference between it is 180
Does the difference in the level of heat between two substances determine the heat transfer rate between the substances?
true
What is the difference between a finished and an unfinished bolt?
One is finished and the other isn't. This is very true.
What is difference between relative motion and true motion in electronic navigation?
In Relative Motion, own ship is fixed at the center of display screen. In True motion, lands are fixed and own ship is moving.
What is equivalent airspeed?
Equivalent airspeed is speed at sea level in which the incompressible dynamic pressure can be produces as if it were at true airspeed. Equivalent airspeed is used to predict aircraft handling.
Does true airspeed increase with altitude?
Yes, it does.
What is True airspeed indicator?
It's an airspeed indicator that compensates for outside temperature and barometric pressure at altitude.
What is the difference between speed over ground and speed over water?
Air speed is the speed through the air (surprise!) and the air is often moving, you can have a strong tailwind or headwind so that will affect your speed over the ground (groundspeed). The speed through the air might be 500mph, and the groundspeed either 550mph or 450mph, if the wind is at 50mph.
What is the limitation of the airspeed indicator?
some V speeds are not indicated, It doesn't show true airspeed or ground speed.
What could describe an airplane's velocity?
The main two useful velocity measurements are... 1. KTAS- Knots (True Airspeed) 2. KIAS- Knots (Indicated Airspeed)
What is the difference between herkimwe diamonds and true diamond?
One difference between Herkimwe diamonds and true diamonds is that the Herkimwe diamonds are softer than true diamonds.
What is the difference between a tale and a story?
A story can be true or not where as a tale is not true.
True or false Declination is the difference between true north and magnetic north?
true
What is the difference between true or false?
True means that it is correct. False means it is not true.
What indicated airspeed should be selected for a particular altitude?
Basically, there are indicated, true and ground speeds. Indicated airspeed takes air pressure differences from a sensor, corrects for pressure altitude (altitude adjusted for barometric pressure) and for temperature to determine true airspeed (speed through the ocean of air). True airspeed is adjusted for winds to get ground speed. There are many factors to consider when selecting a particular air speed. For a particular airplane, fuel efficiency generally decreases with airspeed. Increased airspeed places more demands on piloting skills. If you know all the factors, you can determine the indicated of airspeed in the cockpit. Conversely, if the factors are known, ground speed can be determined from indicated airspeed. Winds aloft, which often change with altitude, are a bigger factor for small planes than for large commercial aircraft on a schedule. For fuel efficiency reasons, when experiencing a tailwind, use a lower indicated airspeed. Conversely, when in a headwind, use a higher airspeed. Either the benefits are greater or the penalty is not as severe when wind is considered. Look at it this way. You would like to stay in a tailwind to get that free push as long as possible, so, fly slower. Different airplanes have different fuel efficiency with airspeed characteristics so the optimum airspeed would vary with the airplane, the priorities of schedule, fuel efficiency and safety as well as weather conditions. Indicated airspeed decreases with altitude, so an altitude correction must be used to get the true airspeed as well as a temperature correction (it gets colder up there). They say speed is money. How fast do you want to go? So, it is a trade off among competing factors.
What is difference between bankers discount and true discount?
The Banker's Gain (BG) is the difference between a banker's discount and a true discount. It is a deduction with simple interest.
