摘要:

Newton’s third law force pairs are sometimes difficult for students to identify, especially when one of the forces produces no discernable acceleration. In the context of a Fermi problem, the third law pairs involved in walking is investigated, paying specific attention to whether the force on the Earth by the walker can impact the Earth’s rotational motion.
