Laws of Motion

"For every action, there is an equal and opposite reaction."

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• Newton's 4th Law

"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

The tendency of an object to resist changes in its motion is...

• inertia
• force
• acceleration
• velocity

Any push or pull on an object.

• force
• velocity 
• inertia
• momentum

The force that opposes motion between two surfaces in contact with each other.

• inertia
• friction
• momentum
• gravity

The force of attraction between all matter.

• inertia
• friction
• net force
• gravity

When all the forces on an object are equal and opposite, & the net force is zero, that's...

• balanced forces
• unbalanced forces
• terminal velocity
• reaction forces

A magician pulls a tablecloth out from under dishes and glasses on a table without disturbing them.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law

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

• The Law of Inertia
• 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.
