streamlined

Definition

Streamlined means having a smooth, curved shape that helps an object move through air or water more easily. Streamlined objects have less drag, which is the force that slows them down as they move through a fluid.

Some examples of streamlined objects include:

  • Fish
  • Birds
  • Airplanes
  • Cars
  • Bullets

Streamlined objects are often found in nature because they help animals and plants move more efficiently. For example, the streamlined shape of a fish's body helps it swim through the water more easily.
