Question

what is SI unit of force​

Answer 1

Answer:

SI unit of force is Newton(N)

Explanation:

We know if force F acting on mass m then acceleration is,

a=F/m

or,F=ma

Now SI unit of mass is "kg" and acceleration is. "m/(s^2)"

Then SI unit of force = 1kg× 1 m/s^2, which is known as NEWTON

Answer 2

SI UNIT OF FORCE :

• A force is a vector quantity defined as a push or a pull on an object.

• Mathematically, force is calculated as the product of mass and acceleration of an object.

• F = m × a

So, the SI unit of force will be :

$[F] = [m] \times [a]$

$\implies [F] = kg \times m/ {s}^{2}$

$\implies [F] = kg \: m/ {s}^{2}$

• Now, kg m/s² can also be written as Newton (N).

$\implies [F] = N$

So, SI unit of force is kg m/s² or Newton (N).
