Details

Here is the corrected text: Pack of 10 ball bearings. Each ball measures 10mm in diameter. Made from high-quality steel, they are built to last. They are great for a wide variety of physics experiments and demonstrations of mechanics, including kinetic and potential energy, velocity, energy conservation, momentum, collisions, inertia, friction, and density/mass. Perfect for use with projectile launchers, roller coaster simulations, collision simulations, ballistic pendulums, second law of motion apparatuses, and inertia demonstration apparatuses. Designed for use in a science laboratory, they are also great for various uses around the home.
