Question

If there were no gravity, the planets would
move in a straight line instead of an orbit
O orbit around Earth instead of the sun
O revolve in perfect circles instead of elliptical orbits
O still on it the sun
(Science 400 semester 2)

Answer 1

Answer:

move in a straight line instead of an orbit

Explanation:

While gravity is the force that maintains the planets' orbit around the sun, inertia states that objects in motion have a tendency to stay in motion. So if there were no gravity then there'd be no force acting on the planets to keep them in orbit, therefore they'd move in a straight line because inertia is still in effect.
