Question

Swimming can be explained by

• A. Newton's law of gravitation
• B. First law of motion
• C. Second law of motion
• D. Third law of motion

Answer 1

The correct option is D

Third law of motion

1. Newton's third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction.
2. When we swim, we apply backward force on the water which in turn applies a force on us in the forward direction. So, we are able to swim. This is an example of Newton's third law of motion.

Swimming can be explained by Newton's third law of motion.
Thus, option (d) is correct.
