Submarines and airplanes have a teardrop shape because this design minimizes drag and enhances hydrodynamic or aerodynamic efficiency. The streamlined form allows for smoother movement through water or air, reducing turbulence and energy consumption. Additionally, the tapered rear helps to reduce wake and improve stability, making these vehicles more effective in their respective environments. This shape optimizes performance and fuel efficiency, which is crucial for long-distance travel.

What shape is a teardrop?

The shape is called the teardrop shape!In 2-dimensions, its parametric equation isx = sin(t)*[sin(t/2)]^my = cos(t) for -pi < t < piThe integer constant, m, changes the shape of the teardrop. At m = 0 the shape is a circle and as m increases the shape gets a pointier the top. m = 3 is about right.The 3-d version is obtained by rotating this shape about the y axis.
