Question

We know that Momentum, P=kg m/s^2, then why not Force, F=kg m/s? .....plz answer it quickly........ ​

Answer 1

$\mathbb{\red{\huge{HEY\:MATE}}}$

$\boxed{HERE\:IS\:YOUR\:ANSWER}$

$\mathfrak{\green{ANSWER:}}$

Momentum = Mass × velocity

= kg.m/s

Force= Mass × acceleration

= kg.m/s^2

They both are different terms.

If any doubts ask me :)

Answer 2

Yeah the SI unit of momentum, p is = kg m/s

This is because, we know that momentum is the product of mass and velocity.

And unit of mass is generally taken in kg and velocity in m/s.

Therefore momentum = kgm/s

Now, force is calculated by multiplying mass and acceleration.

Unit of mass = kg

Unit of acceleration = m/s^2

Hence, SI unit of force is = kg m/s^2

Actually both are not same.. SI unit of momentum is kg m/s and SI unit of force is kg m/s^2 XD

But the SI unit of force is also known as Newton (N) named after Isaac Newton Because of his contribution in classical mechanics.

I know what you're not getting. You are thinking if p = kg m/s then why don't we use kg m/s^2 with force. You can use but in short we just use N (Newton)

Hope I've cleared your doubt :)
