When pressure increases surface area decreases justify by giving examples?

Answer Expert Verified 1. A sharp knife cuts more effectively than a blunt knife as it has a very small surface area and exerts more pressure. 2. A nail has a pointed edge so that it exerts more thrust or pressure.

When surface area decreases pressure will?

how does the decrease in surface area affects the pressure of a given force? By its very definition: Pressure = Force/Area. So for a given force if you decrease the area by a factor of two, then the pressure would increase by a factor of two.

Can we reduce the pressure by increasing area?

Answer: Pressure is inversely proportional to area. The pressure on a surface is inversely proportional to the area of the surface, provided that the force applied on it remains constant. Therefore, the pressure will increase if the area on which it is applied is decreased.

Can we reduce the pressure by increasing area Support your answer with an example?

a pillar of a flyover, dam or bridge have broad base, so that the pressure of the heavy bridge, dam or flyover is distributed on the ground and the pressure of the ground is decreased. Camels have broad feet to reduce the pressure on sand and walk comfortably.

How would you decrease the pressure by increasing the unit area or by decreasing it?

Pressure

1. Pressure is the force per unit area.
2. To increase pressure – increase the force or reduce the area the force acts on.
3. To reduce pressure – decrease the force or increase the area the force acts on.

How can we increase and decrease pressure give examples of each?

1. Trucks have pairs of wheels increasing surface area, so that they do not apply more pressure on the road. 2. When we increase the area of straps of school bags, then pressure decreases and we can carry the bags more comfortably.

How do I reduce the pressure on my surface?

ways to decrease pressure on surface are:

1. Increase the surface area on which force is acting.
2. Decrease the magnitude force.
3. Apply the force at an angle to the surface instead of perpendicular to it.

How do you lower the surface pressure?

To reduce pressure – decrease the force or increase the area the force acts on. If you were standing on a frozen lake and the ice started to crack you could lie down to increase the area in contact with the ice. The same force (your weight) would apply, spread over a larger area, so the pressure would reduce.

How does surface area affect pressure?

You can see that for a given force, if the surface area is smaller, the pressure will be greater. If you use a larger area, you are spreading out the force, and the pressure (or force per unit area) becomes smaller.

Which example increases pressure?

To increase pressure – increase the force or reduce the area the force acts on. To cut up your dinner you can either press harder on your knife or use a sharper one (sharper knives have less surface area on the cutting edge of the blade). To reduce pressure – decrease the force or increase the area the force acts on.

Does increasing surface area increase pressure?

The pressure exerted on a surface by an object increases as the weight of the object increases or the surface area of contact decreases. Alternatively the pressure exerted decreases as the weight of the object decreases or the surface area of contact increases.

What happens to pressure if the area of contact decreases?

Answer: If the area of contact decreases, the pressure increases. pressure is inversely proportional to area that is why pressure increases on decreasing area.

How do you increase the pressure of an object?

Depends on how you are applying force , if the force is applied on point on the area then pressure will increase by decreasing the area but if the applied force is spread over area then you will have to take such area in account if it is also being reduced….

What are some examples of pressure?

Some Practical Examples Let us take an example of pressure: take into consideration a sharp needle, it has a small surface area. However, consider a pencil which is very blunt in the back. It has more surface area than the needle.

How to reduce the pressure on the sand surface?

You reduced the pressure on the sand surface by increasing the contact area. Take an ordinary nail and drive it into a block of wood with a few strokes of the hammer. Now take a rod 2 cm in diameter.

How does pressure depend on the area of the surface?

The pressure on a surface is inversely proportional to the area of the surface, provided that the force applied on it remains constant. Therefore, the pressure will increase if the area on which it is applied is decreased.
