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 heave 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 makes it move.

What is the name of the unit you use to measure force?

• Neutron

• Norton

• Newton

• Nucleus

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

• Skateboard wheels don't spin hast enough to keep them moving very far.

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

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

• Skateboards do not use Newtons to move around ramps.

The greater the friction, the - - - - - -

• lower the gravity.

• the greater the inertia.

• less force needed to move an object.

• more force needed to move an object.

Which of the following is NOT true about mass?

• Objects with greater mass require less force to put in motion

• Objects with less mass require less force to put in motion.

• Objects with greater mass are easier to put in motion.

• Objects with less mass are harder to put in motion.
