Question
Can someone please explain this to me value for the centripetal force acting on the Earth due to the Sun Earth travels on a circular path about the Sun (in reality it's slightly elliptical) and as the 4 Caleulate an approximate Earth-Sun distance in your calculation. What familiat force is acting as famlia fohe centripetal force in this situation? centripetal forc in this situation?your 5. In this experiment, what familiar force is acting as the centripetal force on the object undergoing circular motion?Explanation / Answer
the time taken by earth to rotate around sun is 365 days
T = 365 days = 365*24*60*60 = 31536000 sec
centripetal force = m*r*w^2
w is the angular frequency = (2*pi)/T = (2*3.142)/31536000 = 2*10^-7 s^-1
r is the average distance between sun -earth = 149.6*10^9 m
m is the mass of the earth = 5.98*10^24 Kg
then
centripetal force is F = m*r*w^2 = (5.98*10^24*149.6*10^9*(2*10^-7)^2)
F = 3.58*10^22 N
familiar force acting is gravitational force between Sun and earth
