Dale is learning about the Law of Conservation of Energy and he wants to know what it means. He knows that conserving natural resources means that you do not waste them. For example, he makes sure to turn off the lights when he leaves a room. What is meant by the conservation of energy?

A. Energy cannot be created, but it can be destroyed.

B. Energy cannot be gained or transferred.

C. Energy cannot be created or destroyed.

D. Energy cannot be transferred, but it can be lost.

Final answer:

The Law of Conservation of Energy states that energy cannot be created or destroyed, only changed from one form to another. The correct answer to Dale's question is C. Energy cannot be created or destroyed. This principle is different from the practice of conserving energy by using less.

Step-by-step explanation:

The Law of Conservation of Energy is a fundamental concept in physics which states that the total amount of energy in an isolated system remains constant over time. This law implies that energy can neither be created nor destroyed, but it can be converted from one form to another. For example, electrical energy can be converted to thermal energy when you use a toaster, but the total amount of energy before and after toasting remains the same.

To answer Dale's question, the correct statement reflecting the Law of Conservation of Energy is: C. Energy cannot be created or destroyed. When Dale turns off the lights to conserve electricity, he is practicing energy conservation to use less energy overall, which is different from the Law of Conservation of Energy that describes the behavior of energy in physical processes.

Answer:

A. Energy cannot be created, but it can be destroyed.

Step-by-step explanation:

We are informed from the question about Dale, who is learning about the Law of Conservation of Energy and he wants to know what it means. We are told that He knows that conserving natural resources means that you do not waste them. For example, he makes sure to turn off the lights when he leaves a room.

What is meant by the conservation of energy is "Energy cannot be created, but it can be destroyed". In physics, law of Conservation of Energy states that energy cannot be created or destroyed, but can be transformed from one form to another. This implies that energy can be transferred, one of the instance is in the "swinging of pendulum in upward direction" where kinetic is converted to potential energy

The forms of energy are Chemical, solar, electrical, thermal radiant sound.

However there are two major types of energy which are Kinetic and potential energy.
