Final answer:
Yes, the opening of a door is an example of a moment of force in physics. When you push or pull on a door handle, you are applying a force that causes a change in the angular momentum of the door system.
Step-by-step explanation:
Yes, the opening of a door is an example of a moment of force in physics. When you push or pull on a door handle, you are applying a force that causes a change in the angular momentum of the door system. The effectiveness of the force depends on factors such as the magnitude of the force, the point at which it is applied, and the direction in which it is exerted.
