"Physics Balls" typically refers to interactive physics-based simulations or games where spherical objects behave according to physical laws like gravity, collision, and momentum. These simulations often showcase realistic ball interactions, such as bouncing, rolling, or stacking, and are used for education, entertainment, or engineering demonstrations. In games, players might solve puzzles by manipulating balls with different properties (e.g., weight, elasticity), while educational tools use them to visualize concepts like energy transfer or projectile motion. The term may also describe physical toys (e.g., Newton's cradle) that demonstrate physics principles. Overall, "Physics Balls" emphasizes hands-on exploration of mechanics in a dynamic, engaging way.
