Question

write the mathematical expression of newton's 2nd law with the meaning of the symbols used.​

Answer 1

Answer:

The second law of motion states that any acceleration in an object or body as a result of a force acting on it is directly proportional to the magnitude and direction of the said force. The equation for Newton's second law is as follows - F = m*a,

Answer 2

Answer:

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.
