FreeBody Diagrams"Physics is all about simplification."A freebody diagram (FBD) is a picture that shows ALLthe forces acting on an object.For the sake of simplicity, an object is usually represented by adot <strong>and</strong> only the forces acting on the object are included on thediagram. The forces are represented by arrows.When drawing FBDs, put the tail of the force vectorson the object, with the arrow pointing away from theobject. NEVER draw a force vector pointing towardan object.6
Examples:An apple rests on a desk.A flower pot falls in the absenceof air resistance.A turkey is hung from the ceilingof a classroom.A snail pushes a pumpkin acrossthe floor at constant speed.A car speeds up while travelingon a dirt road.7
