# What Is A Free Body Diagram

What Is A Free Body Diagram. A free-body diagram is a representation of an object with all the forces that act on it. You will find great deal of their usage while studying mechanics and they have equal importance when it comes to other branches A free body diagram is a sketch of the body of interest and the forces acting on the body. How to draw Free Body diagram - YouTube (Beatrice Powers) A free body diagram is a pictorial representation often used by physicists and engineers to analyze the forces acting on a free body. Free body diagrams do not need to be drawn to scale but it can sometimes be useful if they are. Free Body Diagrams (FBD) will be defined.

### A 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.

In your case, you are interested only in the vertical component of the forces acting.

With the help of free body diagram now we can easily find the net force and hence the acceleration of apple. Each body at which you want to apply $\sum F = m a$ you add up vectorially the force components acting on that body. Free body diagrams do not need to be drawn to scale but it can sometimes be useful if they are.
