Mary Law

Mary Law’s law states that the total energy in an isolated system remains constant over time. In simpler terms, energy cannot be created or destroyed, only transformed from one form to another. For example, when you climb a hill, your chemical energy becomes gravitational potential energy, but the total energy stays the same. This principle underpins much of physics and helps us understand processes from mechanical motion to thermodynamics. It’s a fundamental rule that explains how energy flows and changes within systems without any loss or gain overall.
