What is atmospheric pressure?
Pressure exerted by the weight of air is known as atmospheric pressure.
How can we increase the pressure by exerting same force?
Mathematically, pressure is given by,
Pressure =
Pressure can be increased by decreasing the area of the surface on which force is to be applied.
Why is the edge of the nails made sharp?
Edge of nails is made sharp(less area) so that the object experiences more pressure. This makes easier for a person to penetrate the wood with the force of a hammer.
Why do camels have broad feet?
Camels have broad feet i.e., feet having a large are so that the pressure exerted on the sand is less due to their heavy weight.
We know that,
Pressure =
Therefore, camels do not dig deep in the sand dunes and can move freely.
