Speed is related to time it takes to travel a certain space or do something. It is also the quality of what is fast and designates the speed of a movement or the speed of a process.
For Physics, speed is the relationship between a certain distance covered and the time spent on the route. Velocity is a vector quantity represented by a vector that has direction, direction and magnitude.
Distance is measured in meters and time in seconds (m/s) in the SI (International System of Units). It is also usually calculated in kilometers per hour (km/h).
THE average speed, according to physics, is the distance it takes for an object to move, divided by the time it took to travel through this space.
AND wind speed, for example, is determined by the time it takes for air to travel in a certain place. Usually the wind speed helps to indicate weather conditions, signaling rain and storms.
cruising speed on a ship or aircraft it means the ideal speed for a given course, in which it is possible to maintain the maximum and constant speed. In other modes of transport, cruising speed designates the highest efficiency/lowest consumption ratio.
The term "cruising speed" is also applied in other contexts to mean "constant", "no change", "routine" or "monotonous".
In Photography, the shutter speed corresponds to the time the camera's diaphragm remains open exposing the film (or sensor) to light during the photo. Speed controls how much light reaches the sensor by changing the effect of freezing (high speed) or movement (low speed) in photographs. The longer it is open, the more light enters and vice versa.
Speed of light
The speed of light is a concept in physics, used as a way to determine the time it takes for light to propagate through an environment. In a vacuum, the speed of light is constant, that is, it does not suffer interference from other elements and remains the same.
The speed of Light in a vacuum is equivalent to 299 792 458 m/s (meters per second), which gives 1079 252 848.8 km/h (kilometers per hour). The speed of light decreases in material environments, depending on the elements of the environment, the frequency and color of light.
Speed of sound
The speed of sound is another concept in physics, and it is determined by the time it takes the sound wave to travel a certain distance. It is known that at sea level, the speed of sound is 340.29 m/s.
