WHAT IS NEWTON’s  2^ND LAW OF MOTION ????

Acc. TO THIS LAW , THE RATE OF 

CHANGE OF LINEAR MOMENTUM  OF

A BODY IS DIRECTLY PROPORTIONAL  TO THE 

EXTERNAL FORCE APPLIED  ON THE BODY ...

AND THIS CHANGE  ALWAYS TAKE PLACE IN THE 

DIRECTION OF THE APPLIED FORCE .....

THIS LAW IMPLIES THAT WHEN A 

BIGGER FORCE ...

IS APPLIED ON A BODY OF GIVEN MASS , ITS LINEAR MOMENTUM CHANGES OR VISE – VERSA....

THE MOMENTUM WILL CHANGE IN THE DIRECTION OF APPLIED FORCE. TO UNDERSTAND IT FURTHER SUPPOSE THAT.

m = mass of a body

V = velocity of the body

The linear momentum of the body -> P= mv

Let F be the external force   applied on the body in the direction of motion of the body.

P = a small change in linear momentum
      t = a small change in time

1.       rate of change of linear momentum = 

So by 1^st eq. of motion= v-u ÷ t

If the value of k = 1

                          F = ma

which have more mass it will produce more acceleration .

And whose mass is less it will produce less acceleration..

If u want to see the next part of this video i.e. Newton,s 3^rd law 

of motion then...
