Consider applying Newton’s second law to a man riding an elevator (perhaps to calculate his acceleration)....
Q1) Answer all Multiple Choice questions.i) Newton’s 1st law is:A. PHYSICALLY INDEPENDENT of the other two laws of motion and CANNOT be dispensed with as an axiom of Newtonian physics.B. PHYSICALLY INDEPENDENT of the other two laws of motion, but nonetheless it CAN be dispensed with as an axiom of Newtonian physics.C. Actually a SPECIAL CASE of the 2ND LAW. The case when the net force is zero. Therefore, logically we need only two laws of motion. Perhaps for clarity...
