Ya know the way theres a centripetal acceleration on an object moving in circular motion and the force is external?? Well what provides the force acting on a satellite orbiting the Earth?? It not like theres someone up there swinging it!!!

ha true!! but whats the cause of the centripetal force??
kinetic energy
inertia
slowly dissipating

centripetal acceleration?
No, I didn't know that.

centripetal acceleration?
If there is such a thing it might be due to the fact one side of the object is closer to the more significant source of gravity.

ye it has centripetal acceleration..which therefore has a force which is also centripetal because its direction points toward the centre...ur right bout the gravity! id say thats its source of force alright!
Of course, I was referring to the gravity of the Earth.
Gravity is the answer to your question.
