Free-Body Diagrams
 
Part I, Preparation
 
•  You should answer Questions 1 and 2 on the worksheet before you go to lab.  For Question 1 you are to sketch free-body diagrams of you, a table, and a force plate while you are in equilibrium standing on the force plate (which is on the floor), pushing down on a table.  For Question 2 you are to sketch free-body diagrams for you and a force plate while you are jumping (accelerating) up and off a force plate.
 

•  On the worksheet, vertically enlarging the drawing canvas will make it easier to insert arrows and text boxes; you may copy, paste, and modify the given examples in Question 1.  You might need to go to Drawing Tools → Align → Grid Settings to undo object snapping.  Change the colors of the vectors from black to gray for any action-reaction pairs within each of the three sets of sketches.  Use the defined abbreviations in the questions in order to be kind to the graders.

Start Part II as soon as you arrive in lab.
