When a walking person lifts one foot off of the ground, which of these happens?

Question

Quizplus · Accepted Answer

When a person lifts one foot off of the ground while walking, the body leans slightly in the direction of the lifted foot so that the center of gravity shifts over the foot that is still on the ground. This keeps the body balanced and prevents it from falling over. Therefore, option D is the correct answer. Option A is not correct because the body does not lean over the lifted foot, but over the foot that is still on the ground. Option B is not correct because the center of gravity shifts slightly to the foot that is still on the ground. Option C is not correct because the body only leans over the foot that is on the ground, and not over the lifted foot. Option E is not correct because the center of mass is not left behind by the acceleration of the body, but rather shifts slightly to the foot that is on the ground.
