- 2. Multiple Choice
The motion of an object includes the speed of the object and the shape of its path. How does Kepler’s description of the paths of planets compare with Aristotle’s description?
Kepler and Aristotle both state that planets move in circles around the sun.
Kepler and Aristotle both state that planets move in elliptical paths around the sun.
Kepler states that planets move in circles around the sun, and Aristotle states that planets move in elliptical paths around the earth.
Kepler states that planets move in elliptical paths around the sun, and Aristotle states that planets move in circles around the earth.
