Explain Newton all laws |
|
Answer» Answer: FIRST law:-- In an inertial frame of reference, an object either remains at rest or continues to MOVE at a constant velocity, unless acted UPON by a force. Second law:-- In an inertial frame of reference, the vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration a of the object: F = ma. (It is ASSUMED here that the mass m is constant – see below.) THIRD law:-- When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body |
