No, then I'm surprised !! As I always used to wonder about the rotation speed of the Earth around the sun.

And if your answer is yes, then probably you might not be knowing the speed, right ?

Now, Let's calculate the speed of Earth's with which it rotates around the sun, which we call it as one complete revolution.

We know that Earth takes 1 year to revolve around the sun, that is, time,

**t= 8765.813 hours**.Also, we know that the average distance between Sun and the Earth is

Distance travelled by Earth in one year, S=2*pi*149,597,890 km (

**149,597,890 km**, that is we can take that value as radius of a cirlce on which Earth revolve, then, Circumference of the circle, that is,Distance travelled by Earth in one year, S=2*pi*149,597,890 km (

**assuming the the path of Earth in which it revolves is circle**) =

**940329594.3 km**(approximately)**Note:**Here I've used the value of pi as 22/7 ( I know it is not accurate value, though we take in practice for calculation :)

Now we know that velocity or speed, v = S/t

=> v = 940329594.3 km / 8765.813 hours =

**107272 km/hr**(approximately)That is,

**the speed at Earth revolve around the Sun, that is Earth's revolution speed, is 66655.73 miles per hour (= 107272 km/hr).**Isn't it very fast ?? And indeed the fact is that is too fast !!

107272 km/hr wow, that a lot of it

ReplyDeletehi, i liked the way you have approached to solve this one, but to the best of what i know, the orbits of the earth are oval shaped and not circular.... So you actually can't take the distance as perpendicular and calculate the circumference
