Question

Is the law of conservation of energy valid in every situation?

Answer 1

Validation of law of conservation of energy:

1. It states that we can convert energy from one form to another while keeping the overall energy constant. It is impossible to produce or destroy energy. The sum of all kinds of energy in an isolated system remains constant.
2. The law is true in all contexts and for all changes.
3. An isolated system's total energy (E) is equal to the sum of its potential energy (V) and kinetic energy (T).
4. $\mathrm{E}=\mathrm{T}+\mathrm{V}$
5. In an isolated system, total energy E remains constant always.
