Newtons Cradle Conservation Of Momentum And Energy
The graph shows that at the start of the swing ball one has a potential energy value of 0005j and a kinetic energy value of 00001as the ball begins to descend down its arc potential energy decreases as it is being converted in to kinetic energy this is known as an inverse relationship as one value increases the other decreases
