please mark me as brainliest
Explanation:
Newton's third law states that every action has an equal and opposite reaction. This is relevant to walking because when you put your foot on the ground, you are applying a force to it. In doing this, the ground also actually applies an equal force onto your foot, in the opposite direction, pushing you forward.

is the displacement vector. When you walk, this is zero unless your feet are slipping, and therefore the work done is zero.
The idea of work is to keep track of what energy certain forces are adding to the system. While walking, the ground isn’t adding any energy to your motion, its just something to pry off of while your muscles do the work.
