A Mona Lisa isn’t required — if you want to find the forces acting on a cow standing on the side of a hill, feel free to represent the cow as a square (you can add some spots to your square cow if you’re feeling particularly artistic). Introduction to free body diagrams Our mission is to provide a free, world-class education to anyone, anywhere.

Free body diagram (FBD) is a graphical representation of the magnitude and direction of all the forces acting on a body. In a hypothetical situation without external forces (friction and air resistance), only the three remaining forces will act on the vehicle. Even though force is involved, a free body diagram may not help.

In this example following forces are acting on the body. Free body diagrams work best with linear motion. In it we will deal with the methods of relating forces on several bodies which make up a system and with ways of breaking a system into several parts.

Note that the force in the spring is now k(x-y) because the length of the spring. Arrows indicate the position, direction, and size of the force acting. 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.
