Engineering Mechanics According to Newton's first law of motion, Everybody continues in its state of rest or of uniform motion, in a straight line, unless it is acted upon by some external force None of these The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts To every action, there is always an equal and opposite reaction Everybody continues in its state of rest or of uniform motion, in a straight line, unless it is acted upon by some external force None of these The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts To every action, there is always an equal and opposite reaction ANSWER DOWNLOAD EXAMIANS APP
