Worksheet with sixteen different scenarios where students are asked to identify the forces present in each so they can draw the relating free body diagram.
Whenever I do this, I try to demonstrate each scenario at the front of the classroom. For example, I have strings hanging from the ceiling where I can easily attach different masses, springs, pulleys, etc. in an effort to mimic the illustrations shown in the worksheet. With each demonstration, we then go through and discuss what forces are present (per the "Types of Forces" worksheet from the day before), then relate that back to the illustration in the worksheet, and ultimately the free body diagram we will draw.
