Newton's Laws of Motion :RRB NTPC Exam 2016

Newton’s Three Laws of Motion are applicable in our day to day activities. They explain to us exactly that why are things in a state of rest or motion.

Newton’s first law of Motion states that a body continues to maintain its state of rest or of uniform motion unless acted upon by an external force. This first law of motion is also called the law of inertia. An object in motion will remain in uniform motion following a straight line unless it is acted on by an external motion which causes it to change in direction or to decrease its speed. For example a ball will not move unless kicked or a ball will not stop rolling down a slope unless stopped.

Newton’s Second Law of Motion states that acceleration is produced when a force acts on an object with a certain mass. The more the mass of the object, the greater is the force required to move it. For example the force required to move a car will be much greater than the force required to move a cycle. The law is represented by the following formula :

F =M x A

F = Force

M = Mass

           A= Acceleration

Newton’s Third Law of Motion states that to every action there will always be an equal and opposite reaction. This law applies to every thing -living or non – living. Right from the movement of fish in water to birds flying in the sky, from the movement of an airplane to launching of rockets in space, the law is universal in nature.
