Question

Define pressure for the applied force. If the area increases or decreases, then that will be the change in pressure ? Explain and give proper illustrations.

Answer 1

Answer:

Pressure is the force exerted per unit area. Mathematically

$pressure = \frac{force}{ {meter}^{2} }$

Pressure is directly proportional to the applied force and inversly proportional to the area (i.e. If we increase the area the pressure decrease and if we increase the force the pressure increase).

Explanation:

In your practical life we use knife instead of spoon for cutting this is because the area of the sharp side of knife is less than that of spoon THUS it applies more pressure on the object to cut, and hence as the sharpness of knife increase the cutting can be done more easily; by applying less force.

Another example is when you nail into a wall the thinner the nail is the lesser is the force required to push it into the wall this is because the thin nail has a very small tip area and thus it produce more pressure as compared to a large (thick) nail.

Answer 2

Answer:

Pressure is the force exerted per unit area. Mathematically

$pressure = \frac{force}{ {meter}^{2} }pressure= </p><p>meter </p><p>2</p><p> </p><p>force$
