How Do You Work Out Energy Is Equal To Mass X Velocity Of Light,E = MC2 ?
Matter (mass) can be converted to energy. This equation tells us how much energy is released by the total conversion of a unit of mass. 1. Units In the equation; “E” stands for Energy, “m” for mass and “c” for celeritas – “speed” in Latin. To work out the equation you can use any units of mass, time and distance that you want. Speed and energy will end up in those units. I will use grams for mass, seconds for units of time and centimeters for distance. This means that the speed will be in centimeters per second, which is cm/sec (divide the distance by time to get speed). Using these units, the resulting energy units will be in “gm cm^2/sec^2”. Conveniently, those units have a name – ergs* (and is the reason I chose the initial units). 2. Math Any amount of mass can be converted. I’m using one gram because it’s the simplest. For c, the speed of light, we have no choice. It is 29,979,000,000 cm/sec. This is very close to 30,000,000,000 cm/sec so I’ll round it off. We must square this and
