A free body diagram is a visual representation of the forces acting on an isolated object or system. It is a simplified drawing that shows the forces as arrows pointing in the direction of their action, with their magnitudes and directions labeled.
The right FBD is upward because it follows the conventions of drawing a free body diagram. The upward direction is usually chosen as the positive direction, and all forces acting in the upward direction are labeled with a positive sign, while those acting in the downward direction are labeled with a negative sign.
Drawing a free body diagram helps to visualize the forces acting on an object or system, making it easier to understand and analyze the problem. It also helps to identify all the forces involved and their directions, which are essential for applying the laws of motion and solving the problem.
Yes, there can be multiple free body diagrams for one system, depending on the different forces or objects that need to be considered. For example, if a box is pushed along a horizontal surface by a person and also experiences friction, there can be two separate FBDs - one showing the forces acting on the box and the other showing the forces acting on the person.
Free body diagrams are a simplified representation of the forces acting on an object or system, and they have limitations. They do not take into account the size or shape of the object, and they assume that all forces are acting at a single point. Also, they do not consider any non-contact forces, such as magnetic or electric forces.
