Energy+-+Izze

  People ride roller coasters all over the world, but what energy helps it to work? At the beginning of the roller coaster there is a small amount of KE because it is starting to move towards the hill. There is no GPE because it is at the lowest point. As the cart climbs, it gains more and more GPE as it gets higher. At point 1 it has the most GPE out of the whole ride because it is at the highest point possible. After the roller coaster comes down the hill to point 2 it has the least GPE because it is at the lowest point possible. At point 3 the cart is gaining some GPE because it is going up hill therefore going higher. At point 1 there is the least amount of KE because the cart is going the slowest. At point 2 the cart has the most KE because it has just turned almost all the GPE into KE by coming down the steep hill and gained speed. At point 3 the cart is losing KE because by going up the hill it is slowing down. All through out the roller coaster the GPE changes into KE as the speed increases and the KE turns into GPE is the cart slows and goes up hill.
