1. Force is defined as any effort that alters an object's state of motion or shape.
2. According to Newton's third law, every action has an equal and opposite reaction.
3. This means that when one object pushes another with force, the second object pushes back with the same force.
4. A force is a push or pulls on an object caused by its interaction with another object. The newton, symbol N, is the SI unit of force.

Option (A): Push and pull of the door
