Engineering Mechanics
The total momentum of a system of masses (i. e. moving bodies) in any one direction remains constant, unless acted upon by an external force in that direction. This statement is called

Newton's first law of motion
Principle of conservation of momentum
Newton's second law of motion
Principle of conservation of energy
