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 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 None of these 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 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 None of these To every action, there is always an equal and opposite reaction ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics If ‘P’ is the force acting on the body, ‘m’ is the mass of the body and ‘a’ is the acceleration of the body, then according to Newton's second law of motion, P/m.a = 0 P - m.a = 0 P × m.a = 0 P + m.a = 0 P/m.a = 0 P - m.a = 0 P × m.a = 0 P + m.a = 0 ANSWER DOWNLOAD EXAMIANS APP
