Front

Which object has the eccentricity of zero and a single focus?

Back

Circle

Front

What effect does increasing the distance between an ellipse’s foci have on the shape of an ellipse?

Back

Increases eccentricity

Front

Find the eccentricity of the following orbit.

Back

The answer should be calculated based on the diagram, but the diagram does not provide enough information to determine the exact value. The expected answer is likely a value between 0 and 1, but cannot be determined from the image alone.
