Product Description
Experience Newtons First Law in action with this colorful Mass and Inertia model featuring iron, aluminum, and acrylic discs each revealing how mass affects motion It turns a tricky physics law into a visual, hands-on experience, making learning about mass and motion exciting and easy to remember. Spin the discs one by one and observe which keeps rotating the longest. Students quickly discover that heavier masses have greater inertia and resist motion changes.
