Everyday Objects:
* Brick: A brick is a perfect example - it has flat surfaces and sharp edges that catch the wind.
* Beach Ball: While round, a beach ball is not streamlined. It's large surface area means it catches a lot of wind.
* Umbrella: An open umbrella is designed to catch rain, not air. It's shape is incredibly inefficient for moving through the air.
* Shopping Cart: The rectangular shape and large surface area make it very difficult to push at high speeds.
Transportation:
* School Bus: The boxy shape and large size make it very inefficient.
* Box Truck: Similar to a school bus, the flat sides create a lot of drag.
* Old-fashioned Car (like a Model T): While much more aerodynamic than a brick, these cars have a lot of exposed surface area.
Things that are *not* designed to move through the air:
* Building: Buildings are stationary, so their shape is not optimized for air flow.
* Rock: Rocks have irregular shapes, leading to a lot of air resistance.
* Table: Flat surfaces are terrible for moving through the air.
Key Concepts:
* Aerodynamic means designed to reduce drag and improve movement through air.
* Drag is the force that opposes motion through the air.
* Streamlined shapes are often smooth and curved to minimize drag.
