Boomerangs travel in an elliptical path, returning to a skilled thrower.

These move constantly along an elliptical path, sampling the intensity of sunlight, and directing the large leaf to the area of most intensity.

Due to the interaction with the molecule, the electric field vector of the light traces out an elliptical path after passing through the sample.

Such calculations generally result in an elliptical path on a plane defined by some point on the orbit, and the two foci of the ellipse.

Driven by dual orthogonal vibration modes with a phase difference of 90, the contact point between two surfaces vibrates in an elliptical path, producing a frictional force between the surfaces.
