- Use the left and right arrow keys to roll the baseball around (or the left and right buttons in the project while on mobile). Just be sure to click on the white background after using the sliders on a PC! - You can adjust the speed of the rolling and the baseball's size. - You can even trace out the motion of the baseball's tip by clicking or tapping the checkbox in the top right. The motion path can also be erased if the tracing becomes too messy.
Inspired by AP Physics C: Mechanics and AP Calculus BC. Don't worry, though, as no college education is required to know what's happening here. This is a simulation of pure rolling, which is "rolling without slipping [sliding]" along a surface. Feel free to use this in your projects! Note that a baseball (or any other ball) is not needed for this rolling motion to occur. Any object with a round surface (like a cylinder or disk) will do.
