Question

orbit is a curved path an object takes around the planet because 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 path without gravity from another object, like a planet, altering their path. gravity pulls an object with less mass towards an object with more mass. (also why its called an orbit: its a perfect balance of inertia and gravity.) a disruption in this balance can be caused by a change to inertia or gravity. an object will fly off into space if there is too much...
question: which orbital force pulls an orbiting object toward the more massive object?
options: inertia, friction, gravity

Explanation:

Inertia is the tendency of an object to resist changes in motion, not a pulling force. Friction opposes motion between surfaces in contact, not a pulling force toward a massive object. Gravity is the critical force that pulls an object toward another object with more mass (like a planet), as described in the text.

Answer:

gravity
