1Energy cannot be created or destroyed; it only changes from one form to another.
2When solving problems involving energy conservation, always consider the total energy before and after any transformation or transfer of energy. Identify which forms of energy are involved and apply the appropriate equations to find unknown quantities. In exam questions about energy conversion, look for clues indicating changes in height (potential energy) or speed (kinetic energy). Use the conservation principle to set up your calculations. Common mistakes include forgetting frictional losses and incorrectly applying formulas.
3Energy changes form, but the total amount stays constant.
4Keep the physical observation and the reason separate, then connect them clearly.
