Energy stored in a stretched or compressed elastic object
Explanation
Elastic potential energy is defined as the energy stored in an elastic object when it is stretched or compressed.
Common mistake
Confusing Elastic Potential Energy with Work Done
Students often confuse the calculation of elastic potential energy with the work done on the spring, leading to incorrect answers.
Remember that elastic potential energy is specifically calculated using the formula Ee = 0.5 x k x e^2, where Ee is the elastic potential energy, k is the spring constant, and e is the extension. Ensure you are using the correct formula for each context.
