Which of the following statements about energy is true? I. Kinetic energy cannot be transformed into another type of energy. II. Kinetic energy can be transformed into potential energy. III. Potential energy can be transformed into kinetic energy. IV. Potential energy cannot be transformed into another type of energy. (1 point) Responses II and IV only II and IV only I and III only I and III only II and III only II and III only I and IV only
I and III only
Explanation: Kinetic energy can be transformed into potential energy (statement III) and vice versa, but kinetic energy can also be transformed into other types of energy, such as thermal or mechanical energy.
