What is Newton’s Second Law of Motion in Physics

Newton’s Second Law of Motion


The acceleration of a body, “a” is directly proportional to the net force acting upon it F, and inversely proportional to its Mass “m”.




According To The Newton‘s Second law of motion when a force acts on an object it produces an acceleration which is directly proportion to the amount of the force,


So,  F =  ma




F = force [N]

M= mass [kg]

A = acceleration caused by F [mS-2]


  1. Force


Changes the size, shape, state of rest, velocity and/or direction of an object

Force is a vector quantity.


  1. Mass


The quantity of matter contained in a body is called mass.



F = ma

m = F/a




The unit of mass in M.K.S system is Kilogram (kg)


I know that you guessed it and you are absolutely right – this happened in the last century. In those days there was a great shortage of books, and what one could get from the library or from girlfriends was read in one gulp. And then a new dose was needed. This can also be called a kind of addiction. We will talk about this “dependence” today. Why do people read?
