Let’s compare this equation of converting matter and energy to some common conversion equations that have the same form: Note that mass is a measure of the quantity of matter, so the significance of this equation is that matter can be converted into energy and energy can be converted into matter. In this equation, E stands for energy, m stands for mass, and c, the constant that relates the two, is the speed of light (3 × 10 8 meters per second). The remarkable equivalence between matter and energy is given in one of the most famous equations: That would be pretty difficult to believe yet, the universe actually works somewhat like that. The idea that matter or energy can be converted into each other seemed as outrageous as saying you could accelerate a car by turning the bumper into more speed, or that you could create a bigger front seat by slowing down your car. Matter is something we can see and touch, whereas energy is something objects have when they do things like move or heat up. This seemed to contradict what humans had learned over thousands of years by studying nature. Furthermore, energy can also be converted into matter. One of the remarkable conclusions derived by Albert Einstein (see note on Albert Einstein when he developed his theory of relativity is that matter can be considered a form of energy too and can be converted into energy. Trace the nuclear reactions in the solar interiorĪs we have seen, energy cannot be created or destroyed, but only converted from one form to another.Understand the nuclear forces that hold atoms together.Describe the particles that make up atoms.Explain how matter can be converted into energy.By the end of this section, you will be able to:
