Write only a statements for first law and second law of motion
Answers
Explanation:
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
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.
Explanation:
according to 1st law of motion-: if a body is at rest,it will remains at rest and if a body is in motion,it will continue in it's same motion untill and unless an external force is applied on it.
according to 2nd law of motion-: "the rate of change of momentum of a body is directly proportional to the applied external force on it and it is directed toward the direction of applied force.
