According to Newton’s law of __________, an object will keep doing whatever it’s doing, whether sitting still or moving, unless the forces acting on it become __________.

• gravity, stronger

• force, balanced

• inertia, unbalanced

• momentum, constant

• acceleration, zero

What part of Newton’s first law of inertia is demonstrated when a magician pulls the tablecloth out from under a set of dishes?

• An object at rest stays at rest unless acted upon by an unbalanced force.

• Every action has an equal and opposite reaction.

• The net force on an object is the sum of all forces acting on it.

• An object in motion stays in motion unless acted upon by a force.

Newton’s second law of motion shows how force, mass, and acceleration are related. What is the formula for force?

• Force = mass x velocity

• Force = mass x acceleration

• Force = acceleration / mass

• Force = mass + acceleration
