From the beginning to the end of a roller coaster, what happens to the total amount of energy?

• The total amount of energy in the car stayed the same because it lost gravitational potential energy but gained kinetic energy.

• The total amount of energy in the car changed because it gained gravitational potential energy and gained kinetic energy.

• The total amount of energy in the car changed because it lost gravitational potential energy and lost kinetic energy.

• The total amount of energy in the car changed because all of the energy was lost.
