The first step in deriving the mathematical equations that govern a physical system is to draw the free-body diagram(s) representing the system. However, a more sophisticated diagram may be of assistance. A free-body diagram is a visual representation of an object and all of the external forces acting on it, so to draw one you'll have to have this information calculated.

The selection of the body to sketch may be the first important decision in the problem solving process. In a hypothetical situation without external forces (friction and air resistance), only the three remaining forces will act on the vehicle. Arrows indicate the position, direction, and size of the force acting.

The external environment (other objects, the floor on which the object sits, etc.), as well as the forces that the object exerts on other objects, are omitted in a free-body diagram.

It is simply because forces acting on the body will cause the motion on the body but the force is applied by the body will cause the motion on some other body. Free body diagrams are used to show which forces are acting on a body at a particular instant in time. Because object B experiences a component of its weight that pulls it to the left.

I have sent in a simple model to demonstrate this issue to cosmos tech support. From Newton's second law, we know that the sum of the forces acting on a body is equal to the product of the mass of the body and its acceleration. An example of one would be a human body outline template with organs, this is perfect for someone that needs to know where and what all the.
