How would you calculate the speed at which the earth revolves around the sun in m/s?
The average distance of the Earth from the Sun is spproximately
The orbit of the Earth around the sun is roughly circular (more eliptical really, but let's keep it simple), with a period of roughly
So the path that the Earth traverses in
Use the formula
The number of seconds in
#365 * 24 * 60 * 60 = 31536000#
So the tangential velocity of the Earth is approximately:
#(9.4 xx 10^11) / (3.1536 xx 10^7) ~~ 3 xx 10^4 m s^(-1)#
If you want more accuracy, get more accurate figures for the distance of the Earth from the sun at perihelion/aphelion and use a more accurate figure for the orbital period.
