Question

Explain newtons 2law derivation method ​

Answer 1

Explanation:

newtons second law states that:

the rate of change of momentum is directly proportional to net external force applied on a body.

F=k(mv-mu)/t (k is the constant of proportionality)

F=km(v-u)/t

F=kma since v-u/t=a

(it so happens that the experimental value of k is 1)

F=ma

Answer 2

QUESTION:

TO EXPLAIN 2ND LAW OF DERIVATION....?

ANSWER:

HERE IS THE ANSWER

DEFINTION:

Newtons second law states that:

The rate of change of momentum is directly proportional to net external force applied on a body.

SECOND LAW OF MOTION FORMULA:

Let us consider an object of mass m, moving along a straight line with an initial velocity u. Let us say, after a certain time t, with a constant acceleration, the final velocity becomes v. Here we see that, the initial momentum Law Of Motion

• The initial momentum
• P1 = MU
• The final momentum
• P2 =MV

EXPLANATION

F=k (mv-mu)/t  (k is the constant of proportionality)

F=km(v-u)/t

⇒F ∝ ma  {∵ a = v-u/t }

⇒F=k.ma

⇒F=MA (∵k=constant=1)

$F =MA\\FORCE =MASS*ACCELARATION\\HENCE PROVED$
