anemometer is the device used to measure wind speed .There different type of Anemometers . There is one with rotating axel which is designed with cups shaped blades placed on the axel to rotate it
. Another is that uses pressure difference to measure speed and are in shape of flat plates . These plates a have spring balancing the pressure differences between tail and head.
When a wind blows, it exerts more pressure on the tail than the tip.
The speed and direction of a tornado can be determined using Doppler radar by measuring how far the tornado moves between sweeps and in what direction.
speedIn physics:If the direction doesn't matter, the word "speed" is used.If the direction DOES matter, the word "velocity" is used.
The anemometer measures wind speed. A weather vane tells wind direction.
The main difference between speed and velocity involves direction. Velocity involves an object moving in a particular direction.
The wind direction is measured with wind vanes or wind socks. The wind speed is measured with an anemometer.
The sun and the stars. Dead reckoning was used all the time. Dead reckoning is when you know the direction you are heading, the speed you are going and the time traveled. With these you would know where you are at any given time and even project where you should be at a given time. They needed to keep track of wind direction and current speed and direction to make adjustments to their course.
In the study of kinematics, 'acceleration' means any change in the speed or direction of motion.

The speed and direction of a tornado can be determined using Doppler radar by measuring how far the tornado moves between sweeps and in what direction.
You can use the FireWire port for high-speed multimedia devices.

As used in physics, "speed" is just how fast something moves, without considering the direction; whereas "velocity" also considers the direction. In other words, speed is a scalar, while velocity is a vector.
The term "velocity", as used in physics, DOES have an associated direction. Most derived terms, such as "average velocity", also do.
