- Birds and insects: Birds and insects have streamlined bodies and wings that reduce air resistance, enabling them to fly efficiently.
- Race cars and airplanes: Race cars and airplanes have aerodynamic designs to reduce drag and improve performance.
- Fish and dolphins: Fish and dolphins have hydrodynamic bodies that minimize water resistance, allowing them to move quickly and efficiently in water.
- Submarines: Submarines have streamlined shapes to reduce water resistance and enable them to operate underwater.
- Bullets: Bullets are designed with a pointed shape to minimize air resistance and travel at high speeds.
