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 second law of motion Newton's first law of motion Principle of conservation of energy Principle of conservation of momentum Newton's second law of motion Newton's first law of motion Principle of conservation of energy Principle of conservation of momentum ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics In order to determine the effects of a force, acting on a body, we must know Nature of the force i.e. whether the force is push or pull Line of action of the force All of these Magnitude of the force Nature of the force i.e. whether the force is push or pull Line of action of the force All of these Magnitude of the force ANSWER DOWNLOAD EXAMIANS APP
