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

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.

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.

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

According to the law of conservation of energy, the energy neither be created nor be destroyed.

Depending upon its energy and its system it can changes the direction.

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

This is by principle of conservation of linear momentum.
