Principle

A wheel, which can unroll around its axis on two cords, moves a gravitational field. This process is filmed with a video camera. The potential energy, kinetic energy, and rotational energy are converted into one another and determined as a function of time with the aid of the "measure Dynamics" software.

Benefits


High and sturdy set-up

Expressive demonstration of energy conversion

Convert potential energy in energy of rotation, energy of translation, and vice versa

Easy measurement and evaluation via movement tracking software


Tasks


Determination of the moment of inertia of the Maxwell wheel by way of the distance-time relationship.

Determination of the moment of inertia of the Maxwell wheel by way of the velocity-time relationship.

Graphical representation of the potential energy, kinetic energy, and rotational energy as a function of time.
