The sledge is being pulled forward by the applied force F1. Another applied force F2 also acts on the sledge. The frictional force F3 acts opposite to the direction of movement and slows the sledge down. The gravitational force F4 pulls the sledge downward. The elastic force F5 acts when the rope or another elastic part is stretched. The net force F6 is the resultant force acting on the sledge.
