From Latin velocĭtas, the speed is the promptness in movement . For example: “I tried to reach it, but I didn't have enough speed and it escaped”, "We need a forward with greater speed", "The offender crossed the bridge at full speed and could only be caught about ten kilometers later".
Speed is also a vector physical magnitude that reflects the space traveled by a body in a unit of time. He meter per second (m / s) It is your unit in the International System.
The average speed is the average speed in a range of weather . For this it is necessary to divide the displacement by the time it took to do it. For example, if a car took ten hours to travel a distance of 500 kilometers, its average speed was 50 kilometers per hour .
It is important to keep in mind that in all countries there are currently a number of speed limitations when it comes to driving vehicles. So much so that whoever exceeds these limits will have to face a series of consequences such as fines, jobs for the community and even, in very specific cases, prison sentences.
It is known as speed race to the athletics test that consists of running as quickly as possible a certain distance. The most popular speed test is the 100 meters flat or plain, which have the Jamaican Usain Bolt as a record man with a time of 9.67 seconds .
However, there are other speed athletics tests such as 60, 200 or 400 meters. Competitions all of them that have managed to raise the likes of Maurice Greene, the Russian Irina Privalova, the American Florence Griffith-Joyner, the German Marita Koch, the French Marie-José Perec or the American Michael Johnson to the summits of the sport. .
Speed races also take place in motor racing (the speed racing ) and motorcycling (speed motorcycling ). These are sports races in which the objective is to complete a certain number of laps in a circuit in the shortest possible time, or to rotate as many laps in a given time. The Formula 1 It is an example of speed racing.
In the case of this car competition, it would be necessary to underline the important events that have been carried out by pilots such as Michael Schumacher, Sebastian Vettel, Mika Häkkinen, Fernando Alonso or Alain Prost.
The speed at which they go during competitions is so high that unfortunately the crashes or exits of the track produce very serious consequences. Thus, for example, the Brazilian Ayrton Senna died during the San Marino Grand Prix of 1994 as a result of the heavy blow that his vehicle suffered.
The speeds, finally, are the positions of the drive mechanism of a gearbox : “This hill you have to climb it at first speed since it is very steep”.
In addition to all of the above we have to underline the existence of a series of expressions that we use in colloquial language and that use the term that now concerns us. This would be the case of the well-known verbal phrase "confuse speed with bacon", which is used to refer to someone mixing aspects that have nothing to do with each other.
