    Pulley: A pulley is a wheel with a rope around it. It helps us lift or move
                        things easily. We use pulleys in many places. For example, pull a bucket

                        from a well and raise a flag on a flagpole.

                        Inclined Plane: An inclined plane is a flat surface that is slanted. It helps
                        make it easier to move or lift heavy objects from a lower place to a higher

                        place. For example, a ramp used to push a wheelchair or a cart and a slide
                        in a playground.
