And does air resistance depend upon surface area?
Are air resistance and buoyant force same
- Thread starter hasankamal007

In summary, air resistance is the force that opposes the motion of an object through the air, while buoyant force is the upward force exerted by a fluid on an object. They are not the same thing, as they have different causes and effects on objects. Although they both involve the movement of fluids, air resistance is caused by the collision of air molecules with an object while buoyant force is caused by the difference in pressure exerted by a fluid. These forces affect objects differently depending on their shape, size, and density, and can impact the motion of objects by slowing them down, causing them to float, or canceling each other out.

hi hasankamal007! 
no, not even similar … forget it!
yes, the larger the surface area, the greater the air resistance
(it also depends on shape)

So air resistance on an object is different than the buoyant force given by air.
Ok. Thanks a bunch tiny-tim.

FAQ: Are air resistance and buoyant force same
1. What is air resistance and buoyant force?
Air resistance is the force that opposes the motion of an object through the air. It is caused by the collision of air molecules with the surface of the object. Buoyant force, on the other hand, is the upward force exerted by a fluid (such as water or air) on an object placed in it. It is a result of the difference in pressure between the top and bottom of the object.
2. Are air resistance and buoyant force the same thing?
No, air resistance and buoyant force are not the same thing. They are two different types of forces that act on objects in different ways. Air resistance slows down the motion of an object, while buoyant force provides an upward lift to an object in a fluid.
3. How are air resistance and buoyant force related?
Air resistance and buoyant force are related in that they both involve the movement of fluids (air or water). However, they have different causes and effects on objects. Air resistance is caused by the collision of air molecules with an object, while buoyant force is caused by the difference in pressure exerted by a fluid on an object.
4. Do air resistance and buoyant force affect all objects in the same way?
No, air resistance and buoyant force affect objects in different ways depending on their shape, size, and density. Objects with large surface areas, such as parachutes, experience a greater amount of air resistance compared to smaller, more streamlined objects. Similarly, objects with lower density, such as helium balloons, experience a greater amount of buoyant force compared to denser objects.
5. How do air resistance and buoyant force impact the motion of objects?
Air resistance and buoyant force can both impact the motion of objects in different ways. Air resistance can slow down the motion of objects by exerting a drag force, while buoyant force can counteract the force of gravity and cause objects to float. In some cases, these forces may cancel each other out and have minimal impact on the motion of an object.
