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 Newton's second law of motion Principle of conservation of momentum Principle of conservation of energy Newton's first law of motion Newton's second law of motion Principle of conservation of momentum Principle of conservation of energy ANSWER DOWNLOAD EXAMIANS APP
