Question

What is Kepler's second law

Answer 1

Kepler's Second Law, also known as the Law of Equal Areas, states that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. This means that a planet travels faster in its orbit when it is closer to the Sun and slower when it is farther from the Sun. As a result, the area covered in equal time intervals remains constant, leading to an elliptical orbit with varying speeds at different points in the orbit. This law highlights the relationship between a planet's speed and its distance from the Sun, emphasizing that gravitational forces are not constant throughout the orbit.
