Answer
When we are sitting on a chair, several forces act on you at the same time :
- Gravitational force (Weight) : The Earth pulls us downward with a force equal to our weight.
- Normal force : The chair pushes us upward with an equal force to balance our weight. This is why we don’t fall through the chair.
- Frictional force : Friction between us and the chair prevents us from slipping off the chair.
Hence, these forces balance each other, which is why we remain at rest while sitting.

We exert a force when we push or pull a body. Force is exerted when we pull a chair or push a door. Force is measured in newton (N). The given table shows values of five individuals that exerted a force in pushing the same box. Observe the table carefully and then answer the given questions.

(b) Which individual exerted minimum force while pushing the box?
(c) Why do you think the force exerted in pushing the box varies from person to person?
(d) What are the forces involved in pushing a box?
