Question

state the law of conservation of energy​

Answer 1

law of conservation of energy​:

• As we know that the law of conservation of energy​ is, energy cannot be created or destroyed it only can be transformed form one form into another.

• We know that the energy of a system is always constant.

• Energy can not be created and it can not destroy.

• We will transfer it from one form in to other form.

Answer 2

• Energy cannot be generated or destroyed, according to the rule of conservation of energy. It can only be transferred from one type of energy to another.

• Unless energy is introduced from the outside, a system always possesses the same quantity of energy.

• This is especially perplexing in the situation of non-conservative forces, in which energy is transformed from mechanical to thermal while the overall energy remains constant.

• Energy can only be used by converting it from one form to another.

• This is also a statement of the first law of thermodynamics.
