Newton's Third Law

Newton's 3rd law says that when two objects interact, the forces between them will be ________ in magnitude

Newton's 3rd law says that when two objects interact, the forces between them will act in ________ directions

A student stands on the floor. While standing on the floor, he pulls down on a cable attached to weights. If the "action" is him pulling down on the cable, what is the "reaction"

• The weights are lifted up

• He feels tired

• His weight decreases

• The cable pulls him up

A student does the leg press, which involves him pushing on a weighted platform. The force of his press equals the weight of the platform, and the forces act in opposite directions.
Is it correct to say that the applied force and the weight are an example of a Newton's 3rd Law pair?

• Yes

• No

A student drops a basketball onto the floor. According to Newton's 3rd law, why does the ball bounce?

• The student dropped the ball

• The earth pulls the ball down

• The ball presses down on the floor

• The floor presses up on the ball

A bug hits into the windshield of a car. How do the forces on the bug and windshield compare?

• The force on the bug is greater

• The force on the windshield is greater

• The forces on the bug and windshield are equal in magnitude.

According to Newton's 3rd Law, when you want to walk, what makes you move forwards?

• Normal force from you on the ground pushes you forward

• The ground's normal force on you pushes you forwards

• The ground's friction force on you pushes you forwards

• Your friction force on the ground pushes you forwards

The moon orbits the Earth. What forces act on the Moon?

• Air resistance

• Normal Force

• Tension Force

• Gravity Force

• Applied Force

The moon orbits the Earth. How do the forces on the moon and earth compare?

• The moon experiences a greater force than the earth

• The moon experiences a lesser force than the earth

• The forces on the moon and earth are equal in strength

Whenever an object exerts a force on another object, the second object exerts a force of the same magnitude but in the opposite direction to that of the first object.

• Always true

• Sometimes True

• Always false
