Rotational Kinetic Energy

This lab investigates the potential energies for a modified Atwood's Machine, where a disk has been added to the Rotary Motion Sensor pulley.

As the hanging mass (m₂) falls, the lighter mass (m₁) rises, but the combined gravitational potential energy of the two decreases, and this energy is converted into the kinetic energy of the system. This includes not only the linear kinetic energy of the two hanging masses, but also the rotational kinetic energy of the rotating disk.

Featured Equipment

550 Universal Physics System

Universal 550 Physics Experiment Bundle

This system provides a complete set of labs for mechanics, heat, light, sound, and electromagnetism.

550 Universal Interface

550 Universal Interface

The 550 is fast, powerful, and incredibly affordable. It offers half the ports and many of the same features as our 850 Interface in a smaller package.

PASPORT Rotary Motion Sensor

The PASPORT Rotary Motion Sensor measures position, velocity, and angular and linear acceleration.

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
