what is the difference between groundspeed and airspeed?
308422
Airspeed is the vector difference between the ground speed and the wind speed. On a perfectly still day, the airspeed is equal to the ground speed. But if the wind is blowing in the same direction that the aircraft is moving, the airspeed will be less than the ground speed.

The short answer is that velocity is the speed with a direction, while speed does not have a direction. Speed is a scalar quantity -- it is the magnitude of the velocity.

Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction. ... The average velocity is the displacement or position change (a vector quantity) per time ratio.

"Standard Velocity" = subsonic. Usually 1080 fps or a little less. There's also the primer-only rounds which are subsonic and much slower but that's not what "standard" means. "High velocity" = supersonic up to about 1300 fps.

Calibrated Airspeed is indicated airspeed corrected for position installation error. Equivalent Airspeed is calibrated airspeed corrected for compressibility. True Airspeed is equivalent airspeed corrected for temperature and pressure altitude.

Speed is a measure of distance traveled over a certain amount of time, while velocity measures displacement over time, as opposed to distance. ... The rate of change for velocity is acceleration, which is measured in displacement over time over time (e.g., m / s^2).

Velocity is vector quantity but speed is scaler quantity. THE BASIC DIFFERENCE BETWEEN SPEED AND VELOCITY IS: ... SPEED HAS ONLY MAGNITUDE AND NO DIRECTION WHEREAS VELOCITY HAS BOTH MAGNITUDE AND DIRECTION. 2. SPEED IS ALWAYS POSITIVE(THAT IS NON - NEGATIVE AND NON-ZERO) WHEREAS VELOCITY IS EXACTLY THE OPPOSITE.

What is the difference between speed and velocity? Speed is just how fast you travel but velocity is the speed in a given direction.

What is the difference between Speed and Economic Speed? ... The rated speed tells us about the maximum speed which can be achieved by a vehicle or some other machine but the economical speed means the speed limit at which the machine works efficiently with least consumption of fuel. eg-in normal bikes(not racing),the max.

Explanation : Root-mean-square speed, average speed and most probable speed : It measures the speed of particles in a gas. It is defined as the speed of particle is directly proportional to the square-root of temperature of gas and inversely proportional to the square-root of molar mass of gas.

They're all the same speed, with one exception: flying mounts are faster than ground mounts. See, your mounts are in two categories: ground mounts and flying mounts. Your riding skill dictates to how fast: Your ground mounts go.

In the case of wind speed, vector-averaged speeds will never be larger than the scalar-averaged values and will generally be lower. Larger differences will occur with greater wind direction variance, which typically occurs at lower wind speeds (below about 2 meters per second).

3 Answers. angular speed is the rate of change of the angle (in radians) with time, and it has units 1/s, while tangential speed is the speed of a point on the surface of the spinning object, which is the angular speed times the distance from the point to the axis of rotation.

Depending on altitude and airspeed, the seats accelerate upward between 12 and 20 Gs. That's just the upward thrust. Pilots have ejected in speeds exceeding 800 miles per hour (the speed of sound is 767.2 mph) and from altitudes as high as 57,000 feet.

The initial speed of an object simply refers to how fast it is moving when it begins its motion (it doesn't take into account whether it is travelling north, south, left, right, etc.). It is a scalar. The initial velocity of an object, on the other hand, has both a magnitude (speed) and a direction (ie: to the left).

What is the difference between static-dissipative and conductive flooring? ESD floors are categorized based on their electrical resistance properties. ... Conductive floors measure less than or equal to 1.0 x 10E6 ohms. Static-dissipative floors measure above 1.0 x 10E6 and less than or equal to 1.0 x 10E9.
