Question on: SS2 Physics - Mechanics - Laws of Motion

Newton's second law plays a crucial role in the design and operation of elevators. The upward acceleration of an elevator is determined by the net force acting on it, which is the difference between the gravitational force acting downward and the upward force provided by the elevator's motor. By adjusting the motor's force, the elevator can be made to move up, down, or remain stationary. Newton's third law also comes into play as the elevator exerts an equal and opposite force on the passengers when it starts or stops.
