Why does the atmosphere exert pressure?
The atmosphere exerts pressure because of the weight of the air above pushing down on the air below. This pressure is caused by the force of gravity acting on the mass of the air molecules in the atmosphere.
Which liquids and gases exert a buoyant force on objects placed in them?
Liquids such as water and gases such as air exert a buoyant force on objects placed in them. This force is a result of the pressure difference between the top and bottom of the object, pushing it upward.
How is possible for air pressure to exert a vertically upward force on a ceiling?
Air pressure exerts a vertically upward force on a ceiling due to the weight of the air above pushing down on the air below. This pressure difference results in a net force that pushes upward on the ceiling, according to Newton's third law of motion.
How can air exert a force when compressed?
When air is compressed, the molecules are pushed closer together, increasing the density of the air. This results in more collisions between the molecules, which creates a pressure that exerts a force on the surrounding environment. The force exerted by the compressed air is a result of the increase in pressure due to the reduced volume.
How do you work out the pressure that you exert?
You can calculate the pressure you exert by dividing the force you apply by the area over which you apply that force. The formula for pressure is: Pressure = Force / Area. The unit for pressure is typically Pascals (Pa) or Newtons per square meter (N/m^2).
Why does the air exert pressure on the surface of the earth?
Air produces a force on the surface of an object (in this case the earth) because of the movement of the particles that make up air. This force over a defined area is known as pressure.
What types of force that exert pressure?
athmospheric pressure

How does air exert a push or pull?
Air exerts a push or pull through the force of air pressure. When air molecules collide with a surface, they create a force that can push or pull objects. This is how phenomena like wind and air resistance occur.
Does light have force in it?
Light does not have mass, so it does not exert a force by itself. However, light can carry momentum and exert a force on objects it interacts with, such as when light is reflected or absorbed by a surface. This is known as radiation pressure.
Why do fluids exert more force the deeper you go?
imagine that all the air around you is puting pressure on you. Then, when you go into a fluid, you can feel the pressure of the air and the water. The deeper you go, the more pressure is on top of you and eventually, you will get crushed.
Can air crush?
Yes it can. Depending on the range of air pressure between earth and space
Does air exert pressure on air or mercury?
Yes. (see - barometer)
