Rutherford Scattering 2

Description

A ball bearing is released from a small ramp directed towards a potential hill. The ramp may be slid laterally to direct the ball towards any particular portion of the potential well. The trajectory of the ball mimics the Rutherford scattering trajectories seen with protons directed towards a nuclear potential well.
