ring and ball app likely refers to a digital simulation or interactive application used to demonstrate the principle of expansion and contraction of materials with temperature changes. The classic "ring and ball" experiment involves a metal ball and a ring, where the ball is slightly larger than the hole in the ring. When the ball is heated, it expands and no longer fits through the ring. When it cools, the ball contracts and can pass through the ring again.
In an app, this experiment might be simulated to help students understand concepts like thermal expansion and material properties.
