Why does a hot air baloon float?
Raising the air temperature inside the envelope makes it lighter than the surrounding (ambient) air. The balloon floats because of the buoyant force exerted on it. This force is the same force that acts on objects when they are in water
What force makes a hot air balloon rise up into the air?
The upthrust exerted by surrounding air on the balloon.
The force on an area from the push of air is called?
The measure of the force exerted by air molecules on a surface per unit area is air pressure.
Force exerted by the weight of air?
14.7 pounds per square inch
The measure of force with which the air molecules are pushing on a surface?
it is AIR PRESSURE
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?
Air pressure is the force exerted by?
air

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 air in a given are known as?
Air Pressure
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
