Multiple Choice
What is Newton's First Law of Motion?
An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.
An object will accelerate in the direction of the net force acting on it.
For every action, there is an equal and opposite reaction.
An object in motion will eventually come to a stop without any external force.

Multiple Choice
What is the difference between balanced and unbalanced forces?
Balanced forces change an object's motion, while unbalanced forces do not.
Balanced forces do not change an object's motion, while unbalanced forces do.
Balanced forces are stronger than unbalanced forces.
Unbalanced forces always act in pairs, while balanced forces do not.

Multiple Choice
How does mass relate to inertia?
Objects with greater mass have greater inertia.
Inertia is independent of mass.
Objects with less mass have greater inertia.
Inertia increases with speed, not mass.

Multiple Choice
According to Newton's Third Law, if someone jumps off a skateboard, the skateboard will roll backwards because-
the mass of the skateboard is the same as the mass of the person jumping off
the pull of gravity on the person is the same as on the skateboard, regardless of size
the air resistance on the person is great and the friction on the skateboard is small
for the force that sent the person forward, there is an equal force pushing back on the skateboard
