Question

what is the Newtons 2nd law can any body

Answer 1

The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object....

Answer 2

Hlo friend..

Here is ur answer :

Newton's second law of motion :

It states that " rate of change of momentum is directly proportional to force acting on body".

Consider a body of mass 'm' is moving with initial velocity 'u' and after time 't' final velocity of body is 'v' and force acting on body is 'F'.

Initial momentum = Mass × velocity

= mu

Final momentum = Mass × velocity

= mv

Change in momentum

= Final momentum — Initial momentum

= mv — mu

= m ( v — u )

Rate of change of momentum

$= \frac{m(v - u)}{t}$

According to statement,

F is directly proportional to
$\frac{m(v - u)}{t}$


Force is directly proportional to
$m \times \frac{(v - u)}{t}$


$\frac{v - u}{t} = a$


a is acceleration.

Force is directly proportional to m × a

F = kma

Value of k = 1

Force = ma

Force = mass × acceleration.

S. I. Unit of Force is NEWTON (N).
