Can any one explain me about centripetal and centrifugal forces . ?
Is any of these forces naturally help the artificial satellites placed in orbit ?
And also what is the nature of curvature of satellite movement (path).
Reason :
Had heard a joke related to this.
Two toughest jobs for human is ,
Pusher and loader .
Pusher - In the middle of the sea , when ever ship's engine stops working and ship halts ,
then PUSHER is supposed get out of the ship and give a PUSH to make the ship engine start again !
Loader - In the space , whenever satellite goes out of fuel by traveling for long time , You will be send above along with the fuel to load it to the FUEL TANKER OF THE SATELLITE !!!
I heard that fuel is used in / for satellite in real , but what purpose is it used ?
