A satellite orbiting above the earth needs no power source to keep orbiting the earth. The best explanation for this involves the law of inertia. Simply put the law of inertia states A) for every force on an object that object exerts an equal and opposite force back. B) a body in motion will continue in motion unless acted upon by an outside force. C) the net force equals the mass times the acceleration of and object. D) energy cannot be created or destroyed on changed forms.

The law of inertia is the second name for Newton's first law of motion, which states that B) a body in motion will continue in motion unless acted upon by an outside force.

The reason that space crafts do not need to be propelled is because there is no frictional force slowing them down as there would be on earth. This means that the craft keeps moving, according to the law of inertia.

B)

Newton's first law of motion states that a body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. This is also known as the law of inertia. Inertia is the tendency of an object to remain at rest or remain in motion.Newton's first law of motion states that a body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force.
