🔍 Key Concepts

• Law of Conservation of Energy in basic physics • Difference between creating/destroying energy and transforming energy • What it means for a statement to be always true in science

💭 Think About

• Ask yourself: In everyday processes (like engines, batteries, heating water), does energy disappear, appear from nowhere, or change form? • Think about whether scientific laws allow energy to change from one form to another (like electrical to heat) and how that affects the total amount of energy. • Consider which option states a principle you have heard as a fundamental law in physics or engineering, especially regarding the total amount of energy.

✅ Before You Answer

• Verify which choice matches the law of conservation of energy you learned in basic science or physics. • Check if any option incorrectly claims energy cannot be transformed from one form to another (you use this idea all the time in engineering and machinery). • Make sure the correct statement is one that is accepted as a universal principle, not just something that seems true in one example.
