That question is based on newton 1st law of motion. According to this law, every body that time up to not motion then not external force are applied.

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.

According to conservation of energy principle. Energy can neither be created nor be destroyed. It can only be transferred from one form to another.

I think there is something missing that is friction force. If we assume newton 1st law of motion in which friction is neglected statement is true.

Low of energy conservation is energy is a universal property and energy is not distrioid and not created only transform one form to another form.

According to conservation of energy principle. Energy cannot be created nor be destroyed. It can only be transferred from one source to another.

According to the conservation of energy, the energy neither be created and nor be destroyed it can transform one state to another state only.

It is true that energy not created nor destroyed transformation of energy from one form to another possible. So given description is wrong.

There is no description of external momentum and secondly force may be applied in any direction and here only one direction is described.

According to principle of energy conservation, energy can't be created can't be destroyed. The definition not belongs to the statement.
