It states that the total amount of energy in an isolated system remains constant over time. The total energy is said to be conserved over time. For an isolated system, this law means that energy can change its location within the system, and that it can change form within the system, for instance chemical energy can become kinetic energy, but that energy can be neither created nor destroyed.

It is not principle of conservation of energy, it is principle of conservation of momentum.

This should be like this only, the total momentum of a system of masses in any direction remains constant unless acted upon by an external force in any (that) direction.
Momentum will change if we apply force in any direction.
Momentum will change if we apply force in any direction.

Principle of conservation of energy stated that energy can neither be created nor destroy.

The law of conservation of energy is a physical law which states energy cannot be created or destroyed, but may be changed from one form to another.
Another way of stating the law is to say the total energy of an isolated system remains constant or is conserved within a given frame of reference.

According to the principle of conservation of energy.
Energy can neither be created nor be destroyed but can be transformed from one for to another.
But here given is the principle of conservation of momentum with the tagline of conservation of energy.
Therefore the answer is false.
