Greek astronomer Hipparchus of Nicaea (c. 190 – c. 120 BC) also rejected Aristotelian physics and followed Strato in adopting some form of theory of impetus to explain motion. [ 27 ] [ 28 ] The poem De rerum natura by Lucretius ( c. 99 – c. 55 BC ) asserts that more massive bodies fall faster in a medium because the latter resists less, but ...
The theory of impetus [1] is an auxiliary or secondary theory of Aristotelian dynamics, put forth initially to explain projectile motion against gravity. It was introduced by John Philoponus in the 6th century, [ 2 ] [ 3 ] and elaborated by Nur ad-Din al-Bitruji at the end of the 12th century. [ 4 ]
Aristotelian physics is the form of natural philosophy described in the works of the Greek philosopher Aristotle (384–322 BC). In his work Physics, Aristotle intended to establish general principles of change that govern all natural bodies, both living and inanimate, celestial and terrestrial – including all motion (change with respect to place), quantitative change (change with respect to ...
The philosophy of motion is important in the study of theories of change in natural systems and is closely connected to studies of space and time in philosophy. The philosophy of motion was of central concern to Ancient Greek and Roman philosophers, particularly the pre-Socratic philosophers such as Parmenides, Zeno of Elea, Heraclitus and ...
The Physics (Greek: Φυσικὴ ἀκρόασις Phusike akroasis; Latin: Physica, or Naturales Auscultationes, possibly meaning "Lectures on nature") is a named text, written in ancient Greek, collated from a collection of surviving manuscripts known as the Corpus Aristotelicum, attributed to the 4th-century BC philosopher Aristotle.
In physics, gravity (from Latin gravitas 'weight' [1]) is a fundamental interaction primarily observed as mutual attraction between all things that have mass.Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 38 times weaker than the strong interaction, 10 36 times weaker than the electromagnetic force and 10 29 times weaker than the weak interaction.
The theory posits that the force of gravity is the result of tiny particles or waves moving at high speed in all directions, throughout the universe. The intensity of the flux of particles is assumed to be the same in all directions, so an isolated object A is struck equally from all sides, resulting in only an inward-directed pressure but no ...
Since the centrifugal force of the parts of the earth, arising from the earth's diurnal motion, which is to the force of gravity as 1 to 289, raises the waters under the equator to a height exceeding that under the poles by 85472 Paris feet, as above, in Prop. XIX., the force of the sun, which we have now shewed to be to the force of gravity as ...
