If the sun's gravity that holds the Earth in orbit were to suddenly disappear, the Earth would a) keep moving in a circular orbit for a little while before coming to a stop, b) spiral inward towards the sun, c) curve away from the sun, d) move in a straight line and slowly stop or e) move in a straight line at a constant velocity.

Question 3 and 4 are multiple choice

3. If the sun's gravity that holds the Earth in orbit were to suddenly disappear, the Earth would
a) keep moving in a circular orbit for a little while before coming to a stop, b) spiral inward
towards the sun, c) curve away from the sun, d) move in a straight line and slowly stop or e)
move in a straight line at a constant velocity.
4. The moon does not crash into the Earth because a) it is beyond the pull of Earth's gravity, b)
there is zero net force acting on the moon, c) the sun keeps it from being pulled toward the
Earth or d) it is freely falling toward the Earth but its tangential velocity is high enough to
keep it at a near constant distance.
