Question

Where is the roller coaster gaining potential energy?

• A. A to B
• B. C to D
• C. B to C
• D. The roller coaster is always losing potential energy

Answer 1

The correct option is C B to C

Whenever there is a gain in height, then the potential energy increases and when there is loss of height, then the potential energy decreases.
As the roller coaster move from B to C, the final position (C) is at greater height than starting position (B) . So PE increases from B to C.
