III. Impulse

Force is directly proportional to rate of change in momentum
That is,
F = k m(v-u)/t
If k is unity
F= ma
So the correct option is I only,that is option A

f is only proportional to the product of mass and acceleration , it is also proportional to the rate of change in momentum....


force is never proportional to the product of mass and velocity (momentum)

and it is also never proportional to impuls

so the correct ans should be A

please my school , make correction ...
thank u

I'm getting tired of failing questions because myschool's answerss are wrong. i have confirmed the answer to this question and this is my ChatGPT's response:
The correct answer is:

A. I only

Explanation:
Newton's Second Law of Motion states that:

𝐹
=
𝑚
𝑎
F=ma
This means Force (F) is directly proportional to the product of mass (m) and acceleration (a).

Analyzing the given options:
I. The product of mass and acceleration → Correct (This is the definition of Newton’s second law).
II. The product of mass and velocity → Incorrect (Force is not proportional to mass × velocity; instead, momentum (
𝑝
=
𝑚
𝑣
p=mv) is related to force through impulse).
III. Impulse → Incorrect (Impulse is given by
𝐹
×
𝑡
=
Δ
𝑝
F×t=Δp, but force is not directly proportional to impulse).
Thus, the correct conclusion is only I.
Kindly make necessary changes. Thank you.

As force is directly proportional to rate of change in momentum, it is also proportional to the momentum that is F α m(v-u) and proportional to the Impulse F α 1/t and of course to the change in momentum F α ma
