Question

Swimming is an example of which of the following?

(a) Newton’s first law of motion

(b) Newton’s second law of motion

(c) Newton’s third law of motion

(d) Law of inertia

The question was posed to me during an interview.

My question is taken from Gravity topic in section Laws of Motion of Engineering Physics I

Answer 1

The correct answer is (c) Newton’s third law of motion

The explanation is: While swimming, a man pushes water backward and in turn he is pushed forward. Thus for the backward action there is an equal and opposite forward reaction.
