#### Position Vs. Time Investigation

Hello All, I'm an AP Calculus teacher, and I used the attached lab to introduce position vs. time graphs to my students. My school doesn't offer physics after freshmen year and historically students have struggled to translate graphs into the actual motion that they represent. This year, using PocketLab and some magnets, the students were able to create their own position vs. time graphs, and concept mastery has been significantly higher. I'm definitely planning on repeating this lab next...

#### Using VelocityLab in an AP/College Physics Experiment Involving Rotational Dynamics

This experiment is designed for AP Physics and college physics students. It considers a solid cylinder of mass M and radius R that is rolling down an incline with a height h without slipping. Using energy and dynamics concepts, students first derive equations for (1) the speed of the center of mass of the cylinder upon reaching the bottom of the incline, and (2) the acceleration of the center of mass of the cylinder as it rolls down the incline. The free-body diagram at the center shows all...
