This is a demonstration of a 19mm ball rolling (from left to right) up an incline, slowing down, and then speeding up as it rolls down the opposite side. This demonstrates the use of the kinetic energy, potential energy, rolling energy, and friction. The image compiles photos taken every .025 seconds with a flash that illuminates the scene at 40 hz.
