4.4 — Conservation of Energy
Energy cannot be created or destroyed — it can only be transformed or transferred.

🧭 Plot Summary
The principle of conservation of energy states that the total energy of an isolated system remains constant. Energy may transform from one form to another — kinetic to potential, or vice versa — but the total always balances.
In this lesson, you will apply the conservation of energy principle to analyze systems where energy transforms between kinetic and potential forms, and learn to account for work done by external forces.
Why it matters:
Conservation of energy is one of the most powerful tools in physics. It lets you predict motion, speeds, and heights without needing to track every force — just the energy transformations.
