Question

Where do we apply a force while walking?

Answer 1

1. Force: Force is defined as any effort that changes the state of motion or shape of an object.
2. The $\mathrm{newton}$ is the SI unit of force, represented by the symbol N.
3. According to Newton's third law, every action has an equal as well as opposite reaction.
4. Therefore, we exert a force on the ground when stepping or walking, which enables the ground to produce a reaction force to our foot, permitting us to go forward.
