The direction of the arrow represents the direction of the force, and the relative lengths of the arrows represent the relative magnitudes of the forces.\u003Cbr>Consider the following situation:\u003Cbr>\u003Cbr>In the picture, a block is sitting on a ramp. The forces on the block are gravity (straight down), the normal force (perpendicular to and away from the ramp), and friction (parallel to the ramp) .\u003Cbr>In the free-body diagram, the block is represented by a dot. The forces, represented by arrows, are gravity (Fg), the normal force (FN), and friction (Ff) . |\n\nNow consider the following situation of a box that accelerates  to the right as it is pulled across the floor by a rope:  \nFrom the picture and description, we can assume that:  \n• The box has weight, which means gravity is pulling down on it.  \n• The floor is holding up the box.  \n• The rope is pulling on the box.  \n• Friction between the box and the floor is resisting the force from the rope.  \n• Because the box is accelerating to the right, the force applied by the rope must be stronger than the force from friction.  \nIn the free-body diagram for the accelerating box, we again represent the object (the box) as a dot, and the forces (vectors) as arrows. Because there is a net force, we should also include a legend that shows which direction is positive.  \nThe forces are:  \n• Fg = the force of gravity pulling down on the box  \n• FN = the normal force (the floor holding the box up)  \n• FT = the force of tension from the rope. (This might also be designated Fa because it is the force applied to the object. )  \n• Ff = the force of friction resisting the motion of the box.  \nNotice that the arrows for the normal force and gravity are equal in length, because in this problem, these two forces are equal in magnitude.  \nNotice that the arrow for friction is shorter than the arrow for tension, because in this problem the tension is stronger than the force of friction. The difference between the lengths of these two vectors would be the net force, which is what causes the box to accelerate to the right.  \nIn general, if the object is moving, it is easiest to choose the positive direction to bethe direction of motion. In our free-body diagram, the legend in the bottom right corner of the diagram shows an arrow with a “+” sign, meaning that we have chosen to make the positive direction to the right.  \nIf you have multiple forces in the same direction, each force vector must originate from the point that represents the object, and must be as close as is practical to the exact direction of the force.  \nFor example, consider a rock sitting at the bottom of a pond. The rock has three forces on it: the buoyant force ( Fb ) and the normal force (FN ), both acting upwards, and gravity ( Fg ) acting downwards.  \ncorrect  \n☺  \nincorrect  \n􀀯  \nincorrect  \n􀀯  \nThe first representation is correct because all forces originate from the dot that represents the object, the directio","cbCaif0yXS7PR8hF","https://ap.wps.com/l/cbCaif0yXS7PR8hF","pdf",562938,"English","# Free-Body Diagrams: Forces in One Dimension\n## Mastery Objective and Success Criteria\n## Free-Body Diagram Definitions and Examples\n## Accelerating Box Pulled by a Rope\n## Choosing a Positive Direction and Drawing Multiple Forces\n## Common Rock-in-a-Pond Forces and Net Force Cancellation\n## Correct vs Incorrect Free-Body Diagram Representations\n## Steps for Drawing Free-Body Diagrams","[{\"question\":\"What does a free-body diagram use to represent an object and forces?\",\"answer\":\"A free-body diagram represents the object as a dot, and each force as a separate arrow.\"},{\"question\":\"How do you choose the positive direction in a free-body diagram?\",\"answer\":\"When an object is moving, it is easiest to choose the positive direction to be the direction of motion, as indicated by the diagram legend.\"},{\"question\":\"Which forces are typically included for a box pulled across a floor?\",\"answer\":\"Gravity (Fg) acts downward, the floor provides the normal force (FN) perpendicular to the surface, the rope provides tension (FT), and friction (Ff) acts to resist the motion.\"}]","Free-Body Diagrams - Unit: Forces in One Dimension | PDF",1792991003]
