To practice Tactics Box 5.1 Working with friction forces. Although friction is a complicated force, many aspects of it can be described with a simple model. This Tactics Box presents the conditions under which these models are valid and outlines the essential steps in solving friction problems.
Whenever you face a problem involving forces, always start with a free-body diagram.
Learning Goal: To gain practice drawing free-body diagramsWhenever you face a problem involving forces, always start with a free-body diagram.To draw a free-body diagram use the following steps:Isolate the object of interest. It is customary to represent the object of interest as a point in your diagram.Identify all the forces acting on the object and their directions. Do not include forces acting on other objects in the problem. Also, do not include quantities, such as velocities and accelerations, that do...

have to identify all the forces acting such as gravity by drawing
it out. 2nd I have to use that drawing and draw it in a free body

To practice Tactics Box 18.5 Ray tracing for a convex mirror. The procedure known as ray tracing is a pictorial method for understanding image formation when lenses or mirrors are used. It consists in locating the image by the use of just three "special rays." The following Tactics Box explains this procedure for the case of a convex mirror. The diagram below shows the situation described in the problem. The focal length of the mirror is labeled f the scale...
