Description
Teach the two-body problem in your high school physics forces unit with this complete lesson. Students will learn to break a two body system into three free body diagrams: system and each part. They will use Fnet=ma analysis to find tension, acceleration and mass.
Includes: fill-in-the-blank guided student notes, warm-up, exit ticket, and homework.
Vocabulary: system analysis, parts analysis, and tension.
✩ BIG IDEAS OF LESSON ✩
- We can break a system into parts or analyze it as a whole.
- When doing a two-body problem, break it down into 3 FBD's.
- You can often use one of the FBDs to find acceleration and one of the other two to find tension/mass.
✩ SPECIAL NOTES✩
- This lesson is a bit longer than normal ones. I teach students who struggle with math and use this lesson as a way to teach algebra. However, you might want to preview the lesson if you have students who are still learning to solve basic algebra equations.
- I teach these lessons using a document camera because I find it to be most engaging for students. I do intend to go back and add PowerPoints to all of these lessons for those who teach with Powerpoint.

Cassy, I’m so glad to hear this! It can be hard to build patient problem solving, so I’m really happy it worked well for your students.
I hope your school year is going well so far.
All the best,Amanda
