Question

use the students models to identify circle the most likely motion of the moon if the gravitational pull of earth diminishes↓ decreases.

Explanation:

Earth's gravitational pull keeps the Moon in its curved, orbital path. If this gravitational pull decreases, the Moon will no longer be held in its closed orbit and will move in a straight, outward direction away from Earth, as the centripetal force keeping it in orbit is reduced.

Answer:

Circle the second model (the one with the Moon moving in a straight arrow toward/away from Earth in a linear path, not falling straight down or staying in an oval orbit).
