Negative Exponentially Damped Harmonic Motion from a PocketLab Pendulum

Rich ·
This experiment allows one to do a quantitative investigation of the damped harmonic motion of a swinging pendulum. The pendulum is a piece of wood about a yard long from a Michael's hobby shop one end of which has been attached to a PocketLab by a rubber band. The other end is taped to the top of a doorway, allowing the resultant pendulum to swing back-and-forth as shown in the image below. The y-axis is perpendicular to the XZ plane of the swinging pendulum. Therefore, the main item of...

VelocityLab Investigation of Damped Harmonic Motion

Rich ·
This investigation shows how VelocityLab allows for a quick and easy demonstration of damped harmonic motion. The photo below shows the experiment setup as performed by the author. A jellied cranberry sauce can was selected as there is virtually no sloshing of the cranberry sauce as the can oscillates back-and-forth on a curved piece of laminate flooring. The center of the flooring is clamped down to the table with an adjustable wrench. The ends of the laminate flooring are raised a little...

PocketLab on an Oscillating Cart

Rich ·
An oscillating cart with a PocketLab provides an interesting way to study Newton's Second Law of Motion as well as some principles of damped harmonic motion. The apparatus setup is shown in the figure below. The small dynamics cart that can quickly be made from parts included in the PocketLab Maker Kit is shown in its equilibrium position. Rubber bands are attached to each side of the cart and to two ring stands weighted down with some heavy books. It is best to use rubber bands that provide...
