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...

Investigating Ampere's Law for a Long Current Carrying Wire

Rich ·
One of the classes of problems dealing with magnetic fields concerns the production of a magnetic field by a current-carrying conductor or by moving charges. It was Oersted who discovered back in the early 1800's that currents produce magnetic effects. The quantitative relationship between the magnetic field strength and the current was later embodied in Ampere's Law, an extension of which made by Maxwell is one of the four basic equations of electromagnetism. PocketLab, used in conjunction...

Quantitative Experiment to Determine the Relationship Between a Pendulum's Length and Period

Rich ·
PocketLab is a perfect device for determining the quantitative relationship between the length of a pendulum and its period of oscillation. Pendulums of known lengths were made from balsa wood strips such as those available from Michaels and other hobby stores. The photo below shows six such pendulums of lengths 15, 30, 45, 60, 75, and 90 cm alongside a meter stick. The picture shows that PocketLab was taped with double-stick mounting tape to the pendulum whose length is 45 cm. The photo...

Investigating Boyle's Law with PocketLab

Rich ·
With a pressure sensor built into PocketLab, there must surely be some way to investigate Boyle's Law. This law states that pressure and volume of an ideal gas are inversely proportional to one another provided that the temperature and amount of gas are kept constant within a closed system. What is needed is a closed system that is large enough to hold PocketLab in a way that pressure can be sensed while changing the volume of the enclosed gas (in our case, air). Educational Innovations,...
