NEWTON' S LIFE AND LAW - NEWTON SECOND LAW

             NEWTON SECOND LAW

Newton's life was fascinating but his works are much more so.

     

His famous "Principia" or mathematical principles of natural philosophy was published in three large volumes in 1686 and 1687.

Newton thought only scientific concepts so he established these books were at his earlier age.

second law 
    

                The acceleration of a body is proportional to the force that acts on the body and in the same direction as the force that causes the acceleration.

     This law states that force is necessary to produce acceleration and is proportional to it. Now starting and stopping a body, acceleration is always present.

In the case of starting a body, the acceleration is positive. In the case of stopping a body, the acceleration is negative.

what is acceleration?

   The rate of change of velocity is called acceleration.

     If the body changes its velocity acceleration is present other body continues to remain in constant motion. If constant motion acceleration is Not present. 

Force equals mass times acceleration :

So the force of any body is the product of the mass of the body and acceleration of the body in the motion.
