volume_muteAs a planet orbits the sun, a line from the planet to the sun sweeps across equal areas in equal times.
True
False
Correct Answer
True
Explanation
To understand it, refer to the below figure. Suppose that the earth moves from point A to point B in a 2-week period. Later in the year, it is at point C, closer to the sun. The law tells us that during the next 2 weeks, it will go just far enough that the area swept out by an imaginary line to the sun will be equal to the area it swept out when it moved from A to B.
