An object in motion (or at rest) will to stay in motion (or at rest) until an outside force acts upon it.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

• Newton's 4th Law

What does it mean when we say a force is "unbalanced" in the context of Newton's First Law of Motion?

• The force does not change the object's direction of motion.

• The force causes the object to move at a constant velocity.

• The force causes a change in the object's state of motion.

• The force is equal in magnitude and opposite in direction to another force acting on the object.

A picture is hanging on a wall and does not move.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

• None of them

A person not paying attention while skateboarding hits a rock. The skateboard stops...they don't.

• The Law of Inertia / Newton's first law

• The Law of Acceleration

• The Law of Conservation of Momentum

Pushing a child on a swing is easier than pushing an adult on the same swing, because the adult has more mass and requires more force to accelerate.

• Newton's 2nd Law

• Newton's 3rd Law
