A student observes a roller coaster at locations A, B, C, and D on the track. Which statement is true according to the bar graph? (1 point) Responses Both potential and kinetic energy change, but total energy does not change. Both potential and kinetic energy change, but total energy does not change. The roller coaster creates kinetic energy. The roller coaster creates kinetic energy. The roller coaster destroys potential energy. The roller coaster destroys potential energy. The roller coaster creates potential energy, but kinetic energy does not change.

Answer 1

Based on the principles of conservation of energy in a roller coaster system, the correct statement is:

"Both potential and kinetic energy change, but total energy does not change."

In a roller coaster, as it moves along the track, its potential energy (due to height) and kinetic energy (due to speed) continually convert into one another, but the total energy remains constant in a frictionless environment.
