Question

1. a subway passenger is standing inside the subway as it moves to the right. a passenger has dropped motor oil inside the subway car making the floor very slick. the subway car slows down abruptly and you fall forward to the right. which of newton’s laws explains why you fell?

Explanation:

Newton's First Law (Law of Inertia) states that an object at rest will stay at rest and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. In this case, the passenger was in motion (moving to the right with the subway). When the subway slowed down abruptly (an external force acting on the subway), the passenger's body, due to inertia (the tendency to maintain its state of motion), continued to move to the right as there was no significant force (because the floor was slick) to stop the passenger's motion immediately.

Answer:

Newton's First Law (Law of Inertia)
