Which has more air resistance: A flat sheet of paper or a paper airplane?
A. A sheet of paper because it has a wider area
B. A sheet of paper because it has a less wide area
C. A paper plane because it has a less white area
D. Paper airplane because it has a wider area
A. A sheet of paper because it has a wider area
To determine which has more air resistance between a flat sheet of paper and a paper airplane, we need to understand the factors that contribute to air resistance.
Air resistance, also known as drag, is the force that acts against the motion of an object through the air. The magnitude of air resistance depends on several factors, including the shape, size, and velocity of the object.
In this case, the shape and size of the objects are different. A flat sheet of paper has a large area, whereas a paper airplane has a smaller and more streamlined shape. The area of an object is an important factor in determining air resistance because a larger area means more air molecules will interact with the object, resulting in greater resistance.
Based on this understanding, the correct answer would be:
A. A sheet of paper because it has a wider area
Therefore, a flat sheet of paper has more air resistance compared to a paper airplane.
