* Shape: Objects with a streamlined shape will experience less air resistance than objects with a blunt shape. This is because streamlined objects create less turbulence as they move through the air.
* Surface roughness: Objects with a rough surface will experience more air resistance than objects with a smooth surface. This is because the rough surface creates more friction between the object and the air.
* Speed: The faster an object moves, the more air resistance it will experience. This is because the air molecules have less time to get out of the way of the object.
