Masse R. Physics. Gravity and Mass 2ed 2023 torrent

Textbook in PDF format

What is gravity ? What is mass ? Although the motion of a body under the action of gravity is well understood, at the same time and on a more fundamental level, much about the true nature of the physical force known as gravity has remained a deep mystery. Similarly, no clear definition of mass has emerged despite years of study. It is the purpose of this book to explore the natures of gravity and of mass.
