Question

What is the difference between energy conservation and the law of conservation of energy? Give some examples of each.

a) Energy conservation is the same as the law of conservation of energy; no difference.
b) Energy conservation refers to renewable sources; law of conservation of energy is universal.
c) Energy conservation is a local concept; law of conservation of energy is a fundamental principle.
d) Energy conservation is a scientific theory; law of conservation of energy is a hypothesis.

Answer 1

Energy conservation involves practices to reduce energy usage, while the law of conservation of energy is a fundamental principle stating energy can only change forms in an isolated system.

Step-by-step explanation:

The difference between energy conservation and the law of conservation of energy is that the former is concerned with reducing energy use and improving efficiency in energy consumption, whereas the latter is a fundamental principle stating that energy in an isolated system cannot be created or destroyed, only transformed.

As an example of energy conservation, turning down thermostats or using LED bulbs helps to conserve energy by reducing energy consumption. An example of the law of conservation of energy is observed when potential energy is converted to kinetic energy during free fall, but the total energy of the system remains constant.
