The Conservation Laws

Conservation laws are fundamental principles in physics stating that certain properties of isolated systems remain constant over time. For example, conservation of energy means energy cannot be created or destroyed; it only transforms from one form to another. Similarly, conservation of momentum indicates that the total momentum of a system stays the same unless affected by external forces. These laws help us understand and predict how objects and systems behave, ensuring consistent descriptions of natural phenomena across different situations. They are crucial tools in science, providing stability and predictability in the study of the physical world.
