What does Newton's third law of motion state?

For every action there is a reaction of lesser magnitude

For every action there is a reaction that cancels out the action

For every action there is an equal and opposite reaction (correct)

For every action there is a reaction in the same direction

What is the reaction force when a person exerts a force on the water using a paddle in a rowboat?

The paddle exerts a reaction force on the person

The water exerts a reaction force on the person and the rowboat (correct)

There is no reaction force in this scenario

The person and the rowboat exert a reaction force on the water

Why don't the action and reaction forces cancel each other out according to Newton's third law?

Because the forces are exerted by different people

Because the forces have different magnitudes

Because the forces act on different objects (correct)

Because the forces are in the same direction
