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.

In the study of kinematics, 'acceleration' means any change in the speed or direction of motion.

- speed of the wind - direction of the wind

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.
In physics, if both the speed and the direction are specified, the term "velocity" is used.
The collective nouns for tools are a set of toolsor a kit of tools.
No; the change in velocity over time is called acceleration.Speed and velocity are used interchangeably in popular language; in physics, the word "speed" is used for a scalar (that is, when the direction is irrelevant), and "velocity" is used for a vector (that is, when you need both a magnitude and a direction).No; the change in velocity over time is called acceleration.Speed and velocity are used interchangeably in popular language; in physics, the word "speed" is used for a scalar (that is, when the direction is irrelevant), and "velocity" is used for a vector (that is, when you need both a magnitude and a direction).No; the change in velocity over time is called acceleration.Speed and velocity are used interchangeably in popular language; in physics, the word "speed" is used for a scalar (that is, when the direction is irrelevant), and "velocity" is used for a vector (that is, when you need both a magnitude and a direction).No; the change in velocity over time is called acceleration.Speed and velocity are used interchangeably in popular language; in physics, the word "speed" is used for a scalar (that is, when the direction is irrelevant), and "velocity" is used for a vector (that is, when you need both a magnitude and a direction).
