Motion (part I) : "Speed"



Hay guys in this time I back with some English articles and I’m so sorry if my English is too far from good and perfect hehehe and what I mention in this blog was a physic. But don’t worry I just packed it up with easy and general definition and not incluided the MATH ! hehehehe so let we Start
Before you understanding Motion you have to know what is speed. When body moved they have speeds. Just example when I walk from location A to another location like B. It has distance 5 km,  and I spent 2 hours. Anyone could say that I have speed 2,5 km every hour. Nope, that is average speeds, This gives no information about the jorney at all. You don’t know how my instananeous speed is. Instantaneous speed and average speed are two different.  You can got average speeds when you sum up the journey and instantaneous speed gives you  information about the speed in every moment. Speed is the distance that covered by an object with some interval.




                 You must be know about race. Let me take the example about Moto GP. Suppose Valentino Rossi starts with a speed of zero, then it can pick up the speed of  200 km/h in just 4 minute. This is what acceleration means. Acceleration is the rate change of speeds. Accleration tells us how quickly the object switches between two speeds.
To the next time we will discuss about how a body can moved?? And our special guest is Aristotle, Galilleo Galilei and Isaac Newton. See you
