![]() ![]() The objects that are characterized by such forces might be of three types: rigid, non-rigid, and particles. They can be rough sketches as well as freehand drawings, and it is not necessary to draw them to the scale of the actual bodies. In physics, these illustrations have immense importance, as they convert materialistic parameters to non-materialistic or theoretical ones, thereby aiding in simplification. Problems regarding physics-, statistics-, and engineering-related studies are often solved using this concept. ![]() One should keep in mind that these representations only consist of vector quantities, and scalars like distance and speed are not to be drawn in the diagrams. These diagrams are then used to calculate these forces, estimate their directions, and also to thoroughly analyze them. Apart from the acting forces and subsequent work done, the moment magnitudes are also considered to be a part of such diagrammatic representations. In a hypothetical situation without external forces (friction and air resistance), only the three remaining forces will act on the vehicle.Ī free body diagram is defined as an illustration that depicts all the forces acting on a body, along with vectors that are applied by it on the immediate environs. These vectors are that of friction, gravity, normal force, air resistance, and engine driving force. The free body diagram of a car traveling at a constant speed consists mainly of five forces, when considered in an actual situation. ![]()
