PocketLab Joins Ozobot to Study Position, Velocity and Acceleration Concepts

Rich ·
Ozobot ( ozobot.com ) is a tiny one inch diameter line-traveling robot that can be used in conjunction with PocketLab to easily study the physics concepts of position, velocity, and acceleration and their time graphs. PocketLab is simply taped to the top of an Ozobot using double-sided mounting tape. In other words, Ozobot gives Pocket lab a ride. The photo below shows this setup, with Ozobot following a 1/4" heavy black line drawn with a chisel tip marking pen. A magnetic ruler can be...

The Physics of a Falling and Unrolling TP Roll

Rich ·
Yes, that's right--the physics of a falling and unrolling toilet paper roll. This experiment will give students practice in rotational motion of an object and translational motion of its center-of-mass. It will also involve both the kinematics and dynamics of the motion. While it can be done by use of the VelocityLab app, interpretation of the angular velocity data from the PocketLab app is much easier. The figure below shows the apparatus setup for this lab experiment. A ring stand is on a...
