newton law and application of newtons
Answers
Answer:
Newtons first law states that A body continues to be in state of rest or of uniform motion in a straight line unless an external force is applied
Second law states that the rate of change of momentum of a body is directly proportional to the force applied on it and this change in momentum takes place in the direction of force applied
Third law states that to every reaction there is always an equal and opposite reaction...

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 )
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.
The three laws of motion were first compiled by Isaac Newton in his Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687.
Newton used them to explain and investigate the motion of many physical objects and systems. For example, in the third volume of the text, Newton showed that these laws of motion, combined with his law of universal gravitation, explained Kepler's laws of planetary motion.
