Timeline of classical mechanics

Early mechanics

• 4th century BC - Aristotle founds the system of Aristotelian physics, which is later largely disproved
• 4th century BC - Babylonian astronomers calculate Jupiter's position using the mean speed theorem^[1]
• 260 BC - Archimedes works out the principle of the lever and connects buoyancy to weight
• 60 - Hero of Alexandria writes Metrica, Mechanics (on means to lift heavy objects), and Pneumatics (on machines working on pressure)
• 350 - Themistius states that static friction is larger than kinetic friction^[2]
• 6th century - John Philoponus says that by observation, two balls of very different weights will fall at nearly the same speed. He therefore tests the equivalence principle
• 1021 - Al-Biruni uses three orthogonal coordinates to describe point in space^[3]
• 1000-1030 - Alhazen and Avicenna develop the concepts of inertia and momentum
• 1100-1138 - Avempace develops the concept of a reaction force^[4]
• 1100-1165 - Hibat Allah Abu'l-Barakat al-Baghdaadi discovers that force is proportional to acceleration rather than speed, a fundamental law in classical mechanics^[5]
• 1121 - Al-Khazini publishes The Book of the Balance of Wisdom, in which he develops the concepts of gravity at-a-distance. He suggests that the gravity varies depending on its distance from the center of the universe, namely Earth^[6]
• 1340-1358 - Jean Buridan develops the theory of impetus
• 14th century - Oxford Calculators and French collaborators prove the mean speed theorem
• 14th century - Nicole Oresme derives the times-squared law for uniformly accelerated change.^[7] Oresme, however, regarded this discovery as a purely intellectual exercise having no relevance to the description of any natural phenomena, and consequently failed to recognise any connection with the motion of accelerating bodies^[8]
• 1500-1528 - Al-Birjandi develops the theory of "circular inertia" to explain Earth's rotation^[9]
• 16th century - Domingo de Soto suggests that bodies falling through a homogeneous medium are uniformly accelerated.^[10][11] Soto, however, did not anticipate many of the qualifications and refinements contained in Galileo's theory of falling bodies. He did not, for instance, recognise, as Galileo did, that a body would fall with a strictly uniform acceleration only in a vacuum, and that it would otherwise eventually reach a uniform terminal velocity
• 1581 - Galileo Galilei notices the timekeeping property of the pendulum
• 1589 - Galileo Galilei uses balls rolling on inclined planes to show that different weights fall with the same acceleration
• 1638 - Galileo Galilei publishes Dialogues Concerning Two New Sciences (which were materials science and kinematics) where he develops, amongst other things, Galilean transformation
• 1645 - Ismaël Bullialdus argues that "gravity" weakens as the inverse square of the distance^[12]
• 1651 - Giovanni Battista Riccioli and Francesco Maria Grimaldi discover the Coriolis effect
• 1658 - Christiaan Huygens experimentally discovers that balls placed anywhere inside an inverted cycloid reach the lowest point of the cycloid in the same time and thereby experimentally shows that the cycloid is the tautochrone
• 1668 - John Wallis suggests the law of conservation of momentum
• 1676-1689 - Gottfried Leibniz develops the concept of vis viva, a limited theory of conservation of energy
