Days 29-31: Vector Addition Diagrams & CAPM Practical

This was a three-day week since public schools closed on Thursday and Friday for the state teachers union conference.

AP Physics 1: Vector Addition Diagrams

Students started the week by doing Kelly O’Shea’s forces representations card sort. I used the card sort to introduce vector addition diagrams, and students easily recognized key aspects of the VAD. The rest of the week, we worked on applying VADs to solve problems. They are successfully applying the VADs, but aren’t feeling confident in their skills just yet.

A completed forces representations card sort categorized into balanced and unbalanced forces.

Physics: CAPM Practical

After wrapping up some problems using the constant acceleration model, students started working on a practical to figure out where to start a marble on a ramp so that it lands in a passing buggy. We ran out of time for students to test their calculations. While students made good progress, many are uncertain of their skills; I’m hoping that completing the practical on Monday will help them build confidence.
