The kit contains two each aluminum, brass, copper, steel, zinc, and wood. The physics balls have a variety of uses including projectile demonstrations in physical science classrooms. These demonstrations help students explore key concepts in mechanics, such as gravity, momentum, and energy transfer. In addition the balls could be used to teach density and buoyancy concepts by comparing the mass of metal balls made of different materials. Despite having the same volume (since the balls are identical in size), their mass will differ because different metals have different densities.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCollision Experiments - Explore elastic and inelastic collisions by rolling two balls toward each other and observing how momentum and energy are transferred.\u003c\/li\u003e\n\u003cli\u003eConservation of Momentum - Use the balls to demonstrate the law of conservation of momentum in linear motion.\u003c\/li\u003e\n\u003cli\u003eAcceleration and Gravity - Drop the balls from different heights to study free fall motion and gravitational acceleration.\u003c\/li\u003e\n\u003cli\u003eNewton’s Cradle Demonstrations - Create simple setups to show how kinetic energy and momentum transfer between objects.\u003c\/li\u003e\n\u003cli\u003eBalancing and Equilibrium - Use the balls on a balanced beam to demonstrate center of mass and torque.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eProduct Details:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Various\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 25mm balls, 5x5x4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e 42004-12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GSC International","offers":[{"title":"Default Title","offer_id":44377472958529,"sku":"MCAB07J2S2CGZ","price":49.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/6321\/7729\/files\/61kKFgIuEoL.jpg?v=1786466553","url":"https:\/\/toycartusa.com\/products\/gsc-international-42004-12-physics-balls-set-w-12-25mm-physics-balls-a","provider":"ToyCartUSA","version":"1.0","type":"link"}
