Question

What is the SI unit of weight?

Answer 1

Weight:

1.Weight of a body is the gravitational force with which a body is attracted towards the center of the earth.

2. So weight itself is a force having both magnitude and direction and so it is a vector quantity.

3.Mathematically weight is represented as follows : $W=mg$

Where, $W\to$weight of the body

$m\to$mass of the body

$g\to$acceleration due to gravity

4. Since, weight is the gravitational force exerted by the earth on the object, its SI unit is the same as that of force which is $newton\left(N\right)$.

Hence, the SI unit of weight is newton $\left(N\right)$.
