WebDec 9, 2024 · Energy is conserved because the laws of nature are symmetric in time—they do not change from moment to moment. But physics wouldn’t be physics if it did not continually question itself. Not long after Einstein derived his famous formula, he began to create a theory of gravitation, his general theory of relativity. WebThe conservation of energy equation only compares a system’s energy for the final and initial points in time. There may be different combinations of energy between these two points, but the equation we use only considers the final and initial energies. For example, consider dropping a ball on a spring (see Figure 1 below).
