MIT Physics Demo - Potential Energy to Kinetic Energy
By FizziksGuy, 04/22/2013
[color=rgb(51,51,51)][font=arial][size=3]Two identical metal balls are dropped from the same height using an electromagnetic release. One ball is dropped freely, while the other hangs from a string, acting as a simple pendulum. Using two photogates, we see that the vertical velocity of the dropped ball is identical to the horizontal velocity of the pendulum, measured at the same height. Potential energy has been converted to kinetic energy equally in both cases.[/size][/font][/color]
