Newton's 3rd Law Quiz

Which of the following statements apply to Newton's 3rd Law of Motion?

• For every action, there is an equal and opposite reaction

• Forces come in pairs

• Action and reaction forces are the same size, but in opposite directions

• All of the above

A rocket ship taking off from the launching pad illustrates Newton's 3rd Law of Motion because...

• The force is equal to the mass time the acceleration

• The rocket stayed at rest until acted on by an opposing force

• The action of hot gases pushing on the launch pad caused a reaction force

• None of the above

Newton's 3rd Law also helps explain the motion of:

• balloons (when you let go of them and the air moves out)

• cars

• birds

• all of the above

True or False:

When a car going down the road hits a soda can on the road, the force of the soda can on the car is equal to the force of the car on the soda can.

• True

• False

True or False:

When a hammer hits a nail, the force of the hammer on the nail is the same as the force of the nail on the hammer.

• True

• False

When a car hits a soda can on the road, the reason the soda can moves more is because of:

• Newton's 1st Law, which states that an object at rest will stay at rest.

• Newton's 2nd Law, which states that forces move (accelerate) objects with low mass more than objects with greater masses.

When a steel hammer hits a steel nail, the nail applies an equal force on the hammer.

The nail moves (accelerates) more than the hammer because:

• The mass of the nail is smaller than the mass of the hammer

• The hammer is made of different material than the nail
