Your older brother tells you his paper airplane has inertia. What does this mean?

• It has too much resistance to fly more than a few feet from his hand.

• It is too heavy to stay in the air for more than a few seconds.

• It will require a lot of force to get it to fly.

• It will stay in flight unless something stops it, or it will stay still unless something moves it.

Why don’t skateboarders keep flying through the air when they launch off a ramp?

• The force of gravity works against the skateboarders' inertia.

• Skateboard wheels don't spin fast enough to move them very far.

• The skateboarders have no inertia when they launch off a ramp.

• Skateboards do not use Newtons to move around ramps.
