What is friction?

• The force that pulls you to the center of the Earth.

• The force that resists the motion of two surfaces touching.

• The force that wiped out the dinosaurs.

• The force that makes you tired.

What is Newton's First Law of Motion?

• For an object at or in motion, the object will tend to stay at rest or in motion, unless acted upon by an outside force.

• The change in an object's velocity is called acceleration.

• Motion.

• Panda.

What is Inertia?

• The tendency to dance when you listen to your favorite song.

• The tendency to play video games when you open your chromebook.

• The tendency of an object to resist a change in its motion.

• Unbalanced forces.

Which equation represents Newton's Second Law of Motion?

• p = v x m

• a = v + 1/3
