NaRiKa® Elastic/Inelastic Balls

These rubber balls appear identical but differ in elasticity to demonstrate energy conversion.​

• Demonstrate elastic and inelastic collisions and energy transfer
• Model kinetic molecular theory and ideal gases

The elastic and inelastic balls set by NaRiKa® serves as a practical tool for physics educators and students to explore and understand the nuances of energy dynamics. The set comprises two types of black spheres that are visually indistinguishable but differ significantly in their elastic properties. The elastic balls are designed to store minimal energy during collisions, resulting in a high rebound, effectively demonstrating efficient energy conversion. In contrast, the inelastic balls absorb more energy upon impact, leading to minimal or no bounce, thereby illustrating concepts of energy loss and inefficiency in energy transfer.

This stark contrast between the two types of balls underscores the critical role material composition plays in physical interactions. Educators can leverage this set to facilitate hands-on experiments and discussions on topics such as potential and kinetic energy, energy conservation, and material science, making abstract concepts more tangible and comprehensible for students.
