Question

A person is walking on the road. Which of the following observation(s) is/are correct with respect to Newton's third law of motion?

• A. The person is pushing the ground forward.
• B. The ground is pushing the person backward.
• C. The person is pushing the ground backward.
• D. The ground is pushing the person forward.

Answer 1

Answer: (C), (D)

The correct options are
C The person is pushing the ground backward.
D The ground is pushing the person forward.

When a person is walking on the ground, he is pushing the ground backward with some force and as per newton's third law, the ground exerts an equal and opposite force on the person. This reactive force enables the person to move forward.
