Step-by-step explanation:
The Law of Conservation of Energy states that within a closed system, energy can change shape , but it can't be created or destroyed. In other words, the entire amount of energy remains constant. On a roller coaster, energy changes from potential to kinetic and back again repeatedly over and over the course of the ride
Complete Step By Step Answer:
The Law of Conservation of Energy states that within a closed system, energy can change shape, but it can't be created or destroyed. In other words, the entire amount of energy remains constant. On a roller coaster, energy changes from potential to kinetic and back again repeatedly over and over the course of the ride.
For most roller coasters, the gravitational P.E. of the cars at the height of the primary hill determines the entire amount of energy that's available for the remainder of the ride. Traditionally, the coaster cars are pulled up Capitol Hill by a chain; because the cars climb, they gain P.E.
At the highest of Capitol Hill, the cars have a greater deal of gravitational P.E. relative to rock bottom, adequate to the mass of the car times the peak of Capitol Hill. When the cars are released Burns edit 2016 from the chain and start coasting down Capitol Hill, P.E. transforms into K.E. until they reach rock bottom of Capitol Hill.
As the cars ascend the subsequent hill, some K.E. is transformed back to P.E. Then, when the cars descend this hill, P.E. is again changed back to kinetic. This transformation between potential and kinetic continues throughout the ride until it involves a rest at the top.
Note :
Roller coasters are ruled by the Law of Inertia. Since an object at rest stays at rest, at the start of the ride a stationary roller coaster is at rest and can get to be pushed or pulled along to urge it to start.
