Answer 1

Answer:

Plz mark me as BRAINLIEST.

Explanation:

Newton's Second law of motion :- The rate of change of momentum is directly proportional to the force applied on the system.  

Force applied is directly proportional to the product of mass and acceleration .

Let  be the initial and final momentums respectively.

According to newton's second law :-  

pf - pi / t ∝ F  

We know that, Momentum ( P) = mv .

Let v be the final and u be the initial velocity .

Now,  

mv - mu / t ∝ F  

F ∝ m ( v-u) /t

F ∝ ma.  

F = kma.  

Here, K is the proportionality constant. It's value is 1 .

Units of Force are given by the units of mass and acceleration. Units of force is Kgm/s² .

In accordance to honour the contributions of Newton, 1 kgm/s² is termed as 1 Newton.

Hope it helps u....
