Newton's Third Law states that for every action, there is an equal and opposite reaction. This means that when one object exerts a force on another object, the second object will exert an equal force in the opposite direction on the first object.
In elevators, Newton's Third Law can be seen in action when the elevator is moving. As the elevator moves up or down, the cables pull on the elevator car with a certain amount of force. In response, the car exerts an equal and opposite force on the cables, allowing the elevator to move smoothly.
Yes, Newton's Third Law still applies when the elevator is stationary. When you push the button to call the elevator, you are exerting a force on the button. In response, the button exerts an equal and opposite force on your finger.
The weight of the elevator does not affect Newton's Third Law. The law states that the forces between two objects are equal and opposite, regardless of their weights. Therefore, the weight of the elevator does not impact the forces between the elevator car and the cables.
One example of Newton's Third Law in elevators is when the elevator is going down and you feel a slight weightlessness. This is because the force of gravity pulling you down is equal to the force of the elevator pushing you up, creating an equal and opposite reaction.
