Conservation of Energy
... The law of conservation of energy states: the sum of the initial energies is equal to the sum of the final energies. Another way you can think about this is that if you add up all your sources of energy; kinetic, potential, spring and work, they should equal the amount energies in the uses category. ...

Since we have no access to electricity or other forms of energy generation, we use gravitational potential energy to keep the ride working. Since the GPE transfers into KE as the ball moves down the slope and energy ...
