1.	It is easier to open or close a door by pushing it at the edges than by pushing closer to the hinges. Explain.
Answer» Solution :A door is fitted to the door frame using hinges. OPENING or CLOSING of a door means a ROTATION about these hinges. Application of a higher moment of force will facilitate this rotation. If the force applied remains the same the moment of force is higher when the arm is LONGER. So the door is USUALLY pushed farthest from the hinges i.e., at the edges.
