Energy Conservation
Grade 6 · Science · Energy Transfer · Louisiana, USA
Lesson Summary
The law of conservation of energy states that energy cannot be created or destroyed, only changed from one form to another.
Explanation
One of the most important laws in science is that the total amount of energy in a closed system stays the same. Energy can transform from one form to another, but it never just appears or disappears. When it seems like energy is lost, it has usually been converted into thermal energy (heat) that spreads out into the surroundings. For example, when a bouncing ball eventually stops, its kinetic energy has been converted into heat through friction. This law applies to everything in the universe, from tiny atoms to entire galaxies.
Practice Questions
Q1: What does the law of conservation of energy state?
Answer: Energy cannot be created or destroyed; it can only change from one form to another.
Q2: A pendulum swings back and forth and eventually stops. Where did its energy go?
Answer: The kinetic energy was gradually converted into thermal energy (heat) through air resistance and friction at the pivot point.
Q3: If energy cannot be destroyed, why do we need to conserve resources like gasoline?
Answer: Because once chemical energy in gasoline is converted into heat and motion, it spreads out and cannot be easily collected and reused in the same way.
