Pressure exerted by the air around us is called?
14.69 pounds per square inch (psi). 2,115.36 pounds per square foot. 19,038.24 pounds per square yard. 58,972,852,224 pounds per square mile. If you want to calculate the complete gravitational force of Earth, find the area (in square miles) and multiply it by 58,972,852,224. That will give you, in pounds, the complete gravitational force of Earth.
Is air resistance a contact or non contact force?
Air resistance is a contact force because you are in contact with the air in order to apply that force.
If kids were wobbling this rope up and down through pudding instead of air what would change?
The force exerted by the kids to pull the rope up and down would increase. The motion would not be fluid (you wouldn't get a perfect harmonic wave). You're amplitude might change if the kids weren't able to exert the proper amount of force.
What is a force that slows things down in the air?
Whenever any object moves through air (eg an aeroplane) it observes four forces 1 Drag force 2. lift force 3.weight of object 4.thrust created by the propellers or engine of the object. The drag force is directed opposite to the direction of moment of the object and slows the object down.
What keeps a telescope in orbit?
It's the gravitational effect of the Sun combined with the inertia of the planets. Their inertia (Newton's first law of motion) would make the planets move in straight lines, but the gravitational force makes them follow elliptical paths and they orbit the Sun.
Air pressure is the force exerted by?
air
The force exerted by the weight of a column of air on a surface is called?
Air Pressure The force exerted by the air above is called?
What is the force exerted by air in all directions?
The force exerted by air in all directions is called air pressure. It is caused by the collisions of air molecules with surfaces. Air pressure is exerted equally in all directions and decreases as altitude increases.
What is the force exerted by the column of air in all objects?
usa
What force opposes gravity and slows down an object falling through the air?
drag force (frictional force exerted by air) or air reststance
In which direcion is air pressure exerted?
The air pressure is exerted in the direction of the air flow. But this is subjected to the Boyle's law. So Boyle's law is correct. You have add the force exerted by the speed of the air to it.
What is the same meaning as air pressure?
the force exerted onto a surface by the weight of the air
What force exerted by the air tends to slow the movement of a plane?
Drag
What is the upward force exerted by a fluid on any object in the fluid?
it is a air
What is upward force exerted by a fluid on any object in the fluid?
it is a air
A quantity that can change is called what?
Variable
What force makes a hot air balloon rise up into the air?
The upthrust exerted by surrounding air on the balloon.
