No. It is due to CONSERVATION OF MOMENTUM and not conservation of energy. Extra Info - In higher classes when you will read about four-vectors (hence four-velocity, four-momentum etc) the law of conservation of emeren and law of conservation of momentum will be combined into one as law conservation...

It's true. It is the cause of existence in the universe. Law of momentum.

It is applicable in terms of energy conservation when there is system is surrounded by adiabatic wall or collision will elastic otherwise this condition is universal for linear momentum conservation...

yes this is true momentum will conserve unless external force does not work.

If force is acting on a moving body perpendicular to the direction of motion, then what will be its effect on the speed and direction of the body?
The magnitude of velocity shall decrease and direction shall be same till it comes to rest, afterwards it shall move in direction of force with acceleration due to the applied force.
