Newton's Second Law for Rotation

A torque is applied to point masses on a rod mounted on a Rotary Motion Sensor and the resulting angular acceleration is measured and the rotational inertia of the object is calculated. The radius of rotation of the point masses is varied.

Featured Equipment

PASPORT Rotary Motion Sensor

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

Rotational Inertia Accessory

Add the Rotational Inertia Accessory to a PASCO Rotary Motion Sensor (PS-3220 or PS-2120) to study the rotational inertia of a disk, a steel ring, and point masses.

Support

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.
