Question

As the cart moves to the positions along the track, it has varying levels of kinetic and potential energy. However, throughout the entire ride, the SUM TOTAL of potential energy PLUS kinetic energy is always equal. Explain why this is true.

Answer 1

The sum total of potential energy and kinetic energy is always equal in a roller coaster due to the law of conservation of energy.

Step-by-step explanation:

In a roller coaster ride, the sum total of potential energy and kinetic energy is always equal because of the law of conservation of energy. This law states that in a closed system, the total energy remains constant. As the roller coaster moves along the track, it undergoes transitions between potential and kinetic energy, but the total mechanical energy remains the same.
