Meaning of Speed ​​(What is, Concept and Definition)

What is Speed:

How quickly we call the quality of fast .In physics, it refers to the relationship between the distance traveled by a body and time used to cover it .As such, it is a scalar physical magnitude, and can be measured in kilometers, miles or knots per hour.

Although speed is often used as a synonym for speed in ordinary language, no They are always exact synonyms, since speed, which is a magnitude of vector character, considers the direction or direction in which a body or object travels, given that speed, which is a scalar magnitude, does not take into account.p>

Speed ​​in physics

Speed ​​is a scalar magnitude that determines the relationship of the distance traveled by a body or object and the time you need to cover this distance.In this sense, it uses length and time dimensions that can be, depending on the case, kilo meters per hour (k/h) or meters per second (m/s).Unlike speed, it is not a vector magnitude, but represents precisely the celerity module.

Average speed

The average speed is calculated by taking the distance traveled by a body and the time taken to travel it, for example: a person who takes two hours to travel 60 kilometers will be traveling with an average speed of 30 kilometers per hour.

Instantaneous speed

Instantaneous speed is that which is measured at a given moment in the movement of a body at a certain point.It can be measured with a speedometer.

Constant speed

As constant speed is called the one to which a body moves without registering variations in its speed, but always maintaining the same speed.
