Step-by-step explanation:
Surface area and weight both have an impact on the air resistance experienced by paper and card.
Surface Area:
The surface area of an object directly affects the amount of air resistance it experiences. A larger surface area creates more contact with the air molecules, resulting in increased air resistance. In the case of paper and card, if you compare two pieces with the same weight but different shapes or sizes, the one with a larger surface area will experience higher air resistance.
Weight:
The weight or mass of an object also plays a role in determining air resistance. Heavier objects generally experience greater air resistance than lighter objects, assuming other factors such as shape and surface area remain constant. This is because the force of gravity acting on a heavier object is greater, leading to more resistance against its motion through the air.
Combining Surface Area and Weight:
When considering the air resistance of paper and card, both surface area and weight should be taken into account. A larger and heavier piece of paper or card will typically experience higher air resistance compared to a smaller and lighter piece with the same shape. However, the specific design, shape, and aerodynamic properties of the paper or card can also influence air resistance.
It's important to note that air resistance is not solely determined by surface area and weight. Factors such as the texture of the material, its shape, and the speed at which it moves through the air also affect the overall air resistance.
