Question

Define the term weight of a body.

Answer 1

1. The weight of the body is defined as the force with which the earth attracts a body towards the center.
2. It is given by the product of the mass of the body and acceleration due to gravity.

$$\begin{gathered} \mathrm{i}.\mathrm{e}.,\mathrm{Weight}=\mathrm{mass}\times \mathrm{accleration}\mathrm{due}\mathrm{to}\mathrm{gravity} \\ \mathrm{or}\mathrm{W}=\mathrm{mg} \end{gathered}$$

3. As $\mathrm{g}$(acceleration due to gravity) varies due to a number of factors, thus weight of a body also varies. It does not remain the same everywhere.
