Conservation of Energy
Introduction
The principle of conservation of energy states that energy cannot be created or destroyed; it can only be transferred or transformed from one form to another. This fundamental principle underpins much of AQA A Level Physics and is used to analyse a wide range of mechanical systems, from moving vehicles to falling objects and oscillating systems. Students should be able to identify energy transfers and apply conservation of energy to solve quantitative problems.
AQA A Level Physics Specification: 3.4.2.4 Conservation of Energy

With Sarah's help my daughter managed to gain an A* in her Physics A Level exams (almost 100% on paper 2!) and was able to gain entry to UCL. We are so proud and cannot thank Sarah enough.
Sarah transformed my daughter's approach to Physics. Her examiner insight was invaluable for boosting her final GCSE grade from a 7 to a 9.
