Does “electricty” or whatever it’s called that goes into your electric vehicle battery, have mass or weigh anything? My car has a 100KW battery. Is the weight substantially different when it has 0 charge versus when it is fully charged? It seems like a lot of energy goes into the battery, it must add to the net mass of the vehicle?
In: Technology
A charged battery “weighs” more, yes, because it holds potential energy, and the mass-energy equivalence tells us that mass has energy and energy has apparent mass. The relationship between the two is given by E = mc^2
