Newton's Third Law and Action-Reaction Pairs Quiz

What does the first symbol in force notation represent?

• The object creating the force

• The object being acted upon

• The direction of the force

• The magnitude of the force

How do we denote the force exerted by object one on object two?

• F2

• F1

• F21

• F12

Which of the following is a common misconception about Newton's Third Law?

• The law is specific to forces between objects

• The law applies to stock market trends

• Forces always act in pairs

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

What does Newton's Third Law specifically refer to?

• The interaction of forces between two objects

• The relationship between mass and velocity

• The acceleration of a single object

• The gravitational pull of the Earth

In the example of a bug hitting a truck, why does the bug experience a larger acceleration?

• The bug has a larger mass

• The truck exerts a larger force

• The bug has a smaller mass

• The forces are different

Why does a larger object not exert a larger force on a smaller object?

• Because the smaller object moves faster

• Because the forces are equal

• Because the larger object has more mass

• Because the forces are different

What is a common misconception about action-reaction force pairs?

• They exist between two objects

• They exist on a single object

• They are always equal in magnitude

• They act in opposite directions

What is the correct understanding of action-reaction pairs?

• They are created by two objects interacting

• They only occur in gravitational interactions

• They are always unequal

• They exist on a single object

Which of the following is an example of an action-reaction pair?

• A person pushing a box and the box pushing back

• A person standing still

• A car accelerating on a road

• A ball rolling down a hill

How does the force of gravity act between the Earth and a person?

• There is no gravitational force between them

• The person only pulls the Earth up

• The Earth only pulls the person down

• The Earth pulls the person down, and the person pulls the Earth up
