Understanding the Law of Conservation of Energy
The law of conservation of energy is a fundamental principle in physics that states that energy cannot be created or destroyed; it can only be transformed from one form to another. This means that the total energy in an isolated system remains constant.
Why Option B Is Correct
- The statement "The total energy before and after transformation remains the same" is accurate because it reflects the core idea of energy conservation.
- When energy changes forms—such as potential energy converting to kinetic energy during a fall—the overall amount of energy does not change.
Why Other Options Are Incorrect
- Option A: "Energy can be created and destroyed."
- This contradicts the conservation principle, as energy cannot simply vanish or appear.
- Option C: "Energy transformation always leads to a loss of energy."
- While some energy may be converted to less useful forms (like thermal energy), the total amount of energy remains unchanged.
- Option D: "Only kinetic energy is conserved, not potential energy."
- This statement is misleading; both kinetic and potential energy can be converted into one another, but their total combined energy is conserved.
Conclusion
The law of conservation of energy is essential for understanding various physical processes and systems. It emphasizes that while energy can change forms, its total amount within a closed system remains constant, validating option B as the true statement.

The law of conservation of energy states that energy can neither be created nor destroyed, only transformed from one form to another. The total energy in a closed system remains constant before and after any transformation.
