Drawing Free Body Diagrams REVIEW Free Body Diagrams (FBD's) are a tool that we use to identify the forces that are acting on an object. Forces are the pushes or pulls that exist between objects. There are two types of forces, contact and long-range. Contact forces are the forces that exist due to the objects touching one another. The only Long Range forces that we are going to work with are gravitational attraction and electrostatic interactions. This means that there are two questions to ask when identifying forces. (1) What is touching the object? (2) What long-range forces are there? All of the forces are to be named in subscripts by identifying both of the objects involved in the force. The outside object is the first one in the name and the object of the FBD is second in the name. The FBD for a book that is sitting on a table is: Table on Book Draw the Free Body Diagrams for each of the following situations. Earth on Book 1. Pavel skating on a hockey rink at constant velocity. (friction optional) 2. Clarissa bumping the volleyball straight up in the air. 3. Kendall and boat being paddled by Kendall.

Check Your Understanding Suppose that Balto in Example 2.10 leaves the game to attend to more important matter, but Astro Clifford and Dug continue playing. Astro and Clifford’s pull on the toy does not change, but Dug rims around and bites on the toy in a different place. With how big a force and in what direction must Dug pull on the toy now to balance out the combined pulls from Clifford and Astro? Illustrate this situation by drawing a vector diagram indicating all forces involved.
