What are the three laws devised by Johannes Kepler to define the mechanics of planetary motion.

• Law of ellipses

• Law of equals areas

• Law of eccentricity

• Law of harmonies

Which scientist developed the laws of planetary motion?

• Kepler

• Newton

• Galileo

• Copernicus

A deviation of a curve or orbit from circularity is called:

• Law of ellipses

• Foci

• ellipse

• eccentricity

A plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant.

• Law of ellipses

• Foci

• ellipse

• eccentricity

The path of the planets about the sun is elliptical in shape, with the center of the sun being located at one focus.

• Law of ellipses

• Law of equal areas

• Law of harmonies
