United Scientific® Moment of Inertia Kit – Physics Demonstration with Adjustable Mass Wands & Rings, Classroom STEM Learning Set

Make physics concepts come alive with the Moment of Inertia Kit, a hands-on demonstration tool designed for classrooms, labs, and STEM education. This engaging kit allows students to explore how the distribution of mass impacts rotational motion, angular velocity, and inertia.

The set includes two wands and two rings of similar mass and size, yet with different mass distributions. By adjusting the movable sliding weights, learners can directly observe how an object’s center of mass influences its resistance to motion. When the weights are positioned at the ends, the wand or ring requires more effort to rotate; when placed near the center, movement is easier and faster.

This interactive physics kit provides a clear, visual, and tactile way for students to understand rotational dynamics. Ideal for high school and college physics demonstrations, it encourages critical thinking, experimentation, and measurable learning outcomes. The kit comes complete with an activity guide to support lesson planning and classroom demonstrations.

Wand weight: approx. 510 g each

Ring weight: approx. 350 g each
