Question

orbit is a curved path an object takes caused by the perfect balance of two forces: inertia and gravity. inertia is what keeps objects in their current motion - whether theyre still or moving steadily. in orbit, inertia makes objects continue in a straight line unless gravity from another object, like a planet, alters their path. gravity pulls an object with less mass towards an object with more mass. objects stay in orbit as long as there is a perfect balance of inertia and gravity. a disruption in this balance can be caused by changes in inertia or gravity. an object will fly off into space if there is too much inertia for orbit. if there is too much gravity for orbit, an object will fall in towards the center of the more massive object. choose the correct answer. what has to happen for one object to orbit another object? inertia must be greater than gravity. inertia and gravity must be balanced. gravity must be greater than inertia.

Explanation:

The text states that objects stay in orbit as long as there is a perfect balance of inertia and gravity.

Answer:

Inertia and gravity must be balanced.
