Definition of newton's law in English English dictionary

Newton's law of gravitation
Statement that any particle of matter in the universe attracts any other with a force (F) that is proportional to the product of their masses (m1 and m2) and inversely proportional to the square of the distance (R) between them. In symbols: F = G(m1m2)/R^2, where G is the gravitational constant. Isaac Newton put forth the law in 1687 and used it to explain the observed motions of the planets and their moons, which had been reduced to mathematical form by Johannes Kepler early in the 17th century
newton's law of motion
one of three basic laws of classical mechanics
Newton's first law
The observation that objects in motion tend to stay in motion, and objects at rest tend to stay at rest unless an outside force acts upon them
Newton's second law
Newton's observation that the rate of change of the momentum of a body is directly proportional to, and in the same direction as, the net force acting on it
Newton's third law
Newton's observation that to every action (force applied) there is an equal but opposite reaction (equal force applied in the opposite direction)
