The correct statement about energy is:
Energy can be changed from one form to another.
This statement reflects the principle of the conservation of energy, which states that energy can neither be created nor destroyed, but can only be transformed from one form to another.
The other statements are incorrect:
-
Energy can be classified as one of three types: While it is common to categorize energy into potential, kinetic, and chemical forms, energy encompasses many other forms as well (thermal, electromagnetic, etc.).
-
Energy is destroyed when a car uses gasoline: This is incorrect because energy is not destroyed; it is transformed from the chemical energy in gasoline to mechanical energy to power the car.
-
Energy can be created in a power plant: This is also incorrect; power plants convert one form of energy (such as fossil fuels or nuclear energy) into electrical energy, but they do not create energy from nothing.
