Question

2. Which statement best explains what happens to the mechanical energy of the system
(roller coaster) as speed is increasing?
a. The mechanical energy of the system increases, provided there is no loss of energy due to
friction. The energy would transform to kinetic energy when the speed is increasing.

b. The mechanical energy of the system remains constant, provided there is no loss of energy
due to friction. The energy would transform to kinetic energy when the speed is increasing.
c. The mechanical energy of the system increases, provided there is no loss of energy due to
friction. The energy would transform to potential energy when the speed is increasing.
d. The mechanical energy of the system remains constant, provided there is no loss of energy
due to friction. The energy would transform to potential energy when the speed is
increasing.

In Chapter 7, the work-kinetic energy theorem, W = K, was introduced. This equation states that work done on a system appears as a change in kinetic energy.
