p143 contains details for calculation of gravity
1478-1518, Notebook of Leonardo da Vinci (''The Codex Arundel''). A collection of papers written in Italian by Leonardo da Vinci (b. 1452, d. 1519), in his characteristic left-handed mirror-writing (reading from right to left), including diagrams, drawings and brief texts, covering a broad range of topics in science and art, as well as personal notes. The core of the notebook is a collection of materials that Leonardo describes as ''a collection without order, drawn from many papers, which I have copied here, hoping to arrange them later each in its place according to the subjects of which they treat'' (f. 1r), a collection he began in the house of Piero di Braccio Martelli in Florence, in 1508. To this notebook has subsequently been added a number of other loose papers containing writing and diagrams produced by Leonardo throughout his career. Decoration: Numerous diagrams.
Marginalia Uncovered in Leonardo's Famous Codex Arundel Suggests the Renaissance Polymath Theorized Gravity Before Galileo by Jo Lawson-Tancred, February 20, 2023, Artnet News
Despite the crudeness of his experimental setup 500 years ago, da Vinci, Dr. Gharib said, was able to calculate the gravitational constant to an accuracy within 10 percent of the modern value.
Nearly a hundred years before Galileo and two hundred years before Newton, in a series of diagrams and notes in the Codex Arundel, Da Viinci was able to calculate the gravitational constant to an accuracy within 10 percent of the accepted value.
The Codex Arundel, named after a British collector, the Earl of Arundel, who acquired it early in the 17th century. Da Vinci composed the collection of hundreds of papers between 1478 and 1518 — that is, between the ages of 26 and 66 — the year before his death. The papers now reside in the British Library. The collection features his famous mirror-writing as well as diagrams, drawings and texts covering a range of topics in art and science.

The creation of L.H.O.O.Q. profoundly transformed the perception of La Joconde (what the French call the painting, in contrast with the Americans and Germans, who call it the Mona Lisa).
While Americans and Germans call Leonardo da Vinci's painting the Mona Lisa, the French refer to it as La Joconde.

But crucially, he believes the pool at the center of the complex may have also served as a surface to observe and map the stars. The water surface would have mirrored the sky, as water does – none other than Leonardo da Vinci pointed out the attributes of inert standing water when studying the night sky. For one thing, the stars were adored by the Phoenicians, whether as gods or deceased ancestors; and the position of the constellations was of keen interest to the sailors among them for navigation purposes, Nigro points out.
Lorenzo Nigro indicates that the "kothon" of Motya in southern Sicily was a pool of Baal whose surface may have been used to observe and map the stars. He also indicates that the Phoenicians adored the stars potentially as gods or deceased ancestors. This is an example of a potentially false assumption often seen in archaeology of Western practitioners misconstruing Indigenous practices based on modern ideas of religion and culture.
I might posit that this sort of practice is more akin to that of the science of Indigenous peoples who used oral and mnemonic methods in combination with remembering their histories and ancestors.
Cross reference this with coming reading in The First Astronomers (to come) which may treat this in more depth.
Leonardo da Vinci documented the attributes of standing water for studying the night sky.
