Overview Newton's laws of motion
isaac newton (1643–1727), physicist formulated laws newton s laws applied objects idealised single point masses, in sense size , shape of object s body neglected focus on motion more easily. can done when object small compared distances involved in analysis, or deformation , rotation of body of no importance. in way, planet can idealised particle analysis of orbital motion around star. in original form, newton s laws of motion not adequate characterise motion of rigid bodies , deformable bodies. leonhard euler in 1750 introduced generalisation of newton s laws of motion rigid bodies called euler s laws of motion, later applied deformable bodies assumed continuum. if body represented assemblage of discrete particles, each governed newton s laws of motion, euler s laws can derived newton s laws. euler s laws can, however, taken axioms describing laws of motion extended bodies, independently of particle structure. newton s laws hold respect set of frames of reference called newtonian or i...
