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