Question

What is the law of conservation of energy?

Answer 1

• Energy cannot be created or destroyed, only transformed from one form to another
• The total energy in a closed system remains constant
• All forms of energy are interconvertible

Comments

Good sense of understanding keep answering to such innovative and scientific questions. It is very encouraging.

Answer 2

The law of conservation of energy states that energy can neither be created nor destroyed, but can be converted from one form to another. This means that the total amount of energy in a system remains constant, even though the energy may change form.

Answer 3

The law of conservation of energy is a fundamental principle of physics that states energy cannot be created or destroyed, but can only be converted from one form to another. This means that in any physical process, the total amount of energy before and after the process remains the same. 

In other words, energy can be transformed from one form to another, such as from potential energy to kinetic energy, but the total amount of energy in the system remains constant. This principle is a cornerstone of modern physics and is used to derive equations and predict physical phenomena in a variety of fields, from mechanics and thermodynamics to electromagnetism and quantum mechanics.

Answer 4

The law of conservation of energy is a fundamental principle in physics that states that energy cannot be created or destroyed in an isolated system. It is also known as the first law of thermodynamics. According to this law, the total amount of energy in a closed system remains constant over time, though it can change from one form to another.
