Question

Which of the following laws or theories is most often used to explain and predict the velocity values at different locations during a roller coaster ride?

• A. Quantum theory
• B. The law of conservation of momentum
• C. The law of conservation of energy
• D. The law of conservation of angular momentum
• E. The law of universal graviation

Answer 1

The correct option is C The law of conservation of energy

We equate the sum of kinetic energy and potential energy at different locations and thus get the values of the velocity at those locations. That's how, law of conservation of energy helps to determine the velocity values at different locations.
