What best describes the energy in a closed system at the beginning of a day and the energy at the end of the same day? check all that apply. some energy can disappear after it has caused motion. some energy can be changed from one form to another. some energy can be lost to the environment around the system. the total initial energy will be equal to the total final energy. the total initial energy will be greater than the total final energy. friction can cause energy to be destroyed during the day. friction can cause the amount of thermal energy to increase
