Look at this SYSTEM of a rollercoaster.

According to the Law of Conservation of Energy, what happens to the amount of ENERGY in this system?

• The total amount of energy increases due to the speed increasing.

• The total amount of energy decreases due to friction.

• The total amount of energy stays the same due to transformations of different kinds of energy.

• The total amount stays the same. Even though friction slows it down, friction and energy aren't related in any way.
