Newton's Laws

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
• None of them

A person’s body is thrown outward as a car rounds a curve on a highway.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• None of them

Rockets are launched into space using jet propulsion where exhaust accelerates out from the rocket and the rocket accelerates in an opposite direction.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• None of them

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 wearing a seatbelt flies through a car window when someone slams on the breaks because the person’s body wants to remain in continuous motion even when the car stops.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• None of them

Pushing a child on a swing is easier than pushing an adult on the same swing, because the adult has more inertia.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• None of them

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• None of them

An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• None of them

This law is often called "the law of inertia."

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• None of them

A soccer ball accelerates more than a bowling ball when thrown with the same force.

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