In zero gravity, do the laws of motion still apply?

• Yes, objects in motion in space tend to stay in motion unless acted upon by an outside force.

• No, objects cannot be in motion in space because there is no gravity.

• Yes, objects in motion in space do not have inertia.

• No, if you do not have gravity you have no motion.

The way things appear to move depends on the movement of the observer.

• True

• False

Asteroids in space don’t have weight. Do they still have inertia?

• Yes

• No
