Principle of conservation of energy states that energy can neither be created nor be destroyed but can be transformed from one form to another form.

This principle is called conservation of momentum.

According to law of conservation of energy charge cannot be created nor destroyed but transferred from one body to other so if two bodies collide their mass will change automatically whether or not an external forces Are applied.

The statment is related to the newton's second law.

The reason is that total momentum includes linear and angular momentum, since linear momentum is conserved in that direction if external force is not acting in that direction. But angular momentum may or may not be conserved as that force may create torque. Hence total momentum will not be conserve.

Its not law of conversation of energy. It is a part off statement from newton's law.

The statement is newton's first law.

Newtons 2 law and law of conservation of energy combined. So it is false statement.

The statement is actually true. But It explains "Law of conservation of Momentum" not the Energy.

Law of conservation of energy system neither be created nor be destroyed.
