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.

Here it is Stated simply priciple of conservation of momentum, Not energy.

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.

False.
According to the law of conservation of momentum, the total momentum of a system remains constant in a given direction if no external force acts on the system in that direction.

Principle of conservation of energy states that energy can neither be created nor be destroyed.

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.
