5Ee4 Solar Power – Solar Model Car
The concept of solar power:
Energy can neither be created nor destroyed. And it does not change over time. The total energy remains constant throughout all energy conversions. Therefore, a common unit of energy is called “Joule”.
Energy can neither be increased nor decreased. Thus, “equivalent exchange” among different energy forms is called “energy conservation law”.
Solar energy is huge; its light and heat energy can transfer to other energy forms such as kinetic energy.
