Which law does this diagram show?

Question

Kepler's Second Law

a
Kepler's second Law: Law of Equal Areas
b
Newton's first Law: everything in motion will stay in motion unless acted upon by an outside force
c
Kepler's Third Law: radius cubed is proportional to orbital period squared
d
Newton's Law of Universal Gravitation

Answer 1

The diagram you are referring to likely illustrates Kepler's Second Law, also known as the Law of Equal Areas. This law states that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time, meaning that a planet moves faster when it is closer to the Sun and slower when it is farther away.

Therefore, the correct answer is:

a. Kepler's second Law: Law of Equal Areas.
