Frequently Asked Questions
How does energy conservation work in physics?
The law of conservation of energy states that energy cannot be created or destroyed, only transformed. In a closed system, total energy remains constant. For example, a falling object converts potential energy (mgh) to kinetic energy (0.5mv^2). At any point, KE + PE = total mechanical energy.
