## noah 4 years ago what is a free-body diagram?

1. heisenberg

a free body diagram is just a simple way to see all forces affecting an object. these forces will typically include the force of gravity, the normal force, and any other forces exerted by / on the object

2. noah

what is normal force?

3. heisenberg

check yr other question :)

The Normal Force is the component, perpendicular to the surface of contact: http://upload.wikimedia.org/wikipedia/commons/c/c7/Incline.svg

Here's one FBDO

Careful... a free-body diagram should only show forces acting ON the body, not forces exerted by the body on some other body. The key to forces is keeping straight who/what they are acting ON.

Free body diagram shows all forces acting on the body - external ones and the ones coming from the constraints, points on the body by which it is connected with other bodies. Examples are: forces from pin joints, surfaces in a contact with a body etc.They come from the third law of dynamics.

FBD is actually a simple diagram to clearly show all the forces acting on a body
