One specific detail in Physical Science is the concept of the law of conservation of energy. This law states that energy cannot be created or destroyed, but it can only change from one form to another. For example, when a light bulb is turned on, electrical energy is converted into light energy and heat energy. The total amount of energy remains the same, but it changes form. This principle helps scientists understand how energy works in many systems, such as machines, power plants, and even in natural processes like photosynthesis and the movement of objects.
