These first few questiоns аre relаted tо Free Bоdy Diаgrams. To best answer these questions: 1.Get a piece of paper and something to write with. You will be drawing several free body diagrams in this DIY activity. 2. Watch the video on Free Body Diagrams by The Physics Classroom on YouTube. 3. Once you have watched the video, you may proceed to the next question.
