Which of the following is the correct formula to calculate weight (W) of an object having mass 'm'?

W = m × g

Earth attracts every object with a certain force and this force depends on the mass (m) of the object and the acceleration due to the gravity (g). The weight of an object is the force with which it is attracted towards the earth.

We know that F = m × a

that is, F = m × g

The force of attraction of the earth on an object is known as the weight of the object. It is denoted by W.

Substituting the same, we have W = m × g
