One fundamental physics lesson is the concept of conservation laws. Conservation laws state that certain quantities remain constant in a closed system, regardless of any internal changes or interactions within that system. These laws are based on fundamental principles of physics and have wide-ranging applications across various branches of the field.
One of the most well-known conservation laws is the law of conservation of energy, which states that energy cannot be created or destroyed but can only be transferred or transformed from one form to another. This principle underlies our understanding of energy in various forms, such as kinetic energy, potential energy, and thermal energy.
