Question

what is law conservation of energy?​

Answer 1

Explanation:

In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. ... For systems which do not have time translation symmetry, it may not be possible to define conservation of energy

Answer 2

The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another

FORMULA =$\boxed{\boxed{k_1+u_1=k_2+u_2}}$
