  2. Newton's laws of motion - Wikipedia

    en.wikipedia.org/wiki/Newton's_laws_of_motion

    Newton's laws of motion are three physical laws that describe the relationship between the motion of an object and the forces acting on it. These laws, which provide the basis for Newtonian mechanics, can be paraphrased as follows: A body remains at rest, or in motion at a constant speed in a straight line, except insofar as it is acted upon by ...

  3. Newton's law of universal gravitation - Wikipedia

    en.wikipedia.org/wiki/Newton's_law_of_universal...

    Assuming SI units, F is measured in newtons (N), m 1 and m 2 in kilograms (kg), r in meters (m), and the constant G is 6.674 30 (15) × 10 −11 m 3 ⋅kg −1 ⋅s −2. ‍ [11] The value of the constant G was first accurately determined from the results of the Cavendish experiment conducted by the British scientist Henry Cavendish in 1798 ...

  4. Newton-metre - Wikipedia

    en.wikipedia.org/wiki/Newton-metre

    141.6 in oz. The newton-metre or newton-meter (also non-hyphenated, newton metre or newton meter; symbol N⋅m[ 1] or N m[ 1]) [ a] is the unit of torque (also called moment) in the International System of Units (SI). One newton-metre is equal to the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm ...

  5. Spring scale - Wikipedia

    en.wikipedia.org/wiki/Spring_scale

    Spring scale. A spring scale, spring balance or newton meter is a type of mechanical force gauge or weighing scale. It consists of a spring fixed at one end with a hook to attach an object at the other. [1] It works in accordance with Hooke's Law, which states that the force needed to extend or compress a spring by some distance scales linearly ...

  6. Hooke's law - Wikipedia

    en.wikipedia.org/wiki/Hooke's_law

    In physics, Hooke's law is an empirical law which states that the force ( F) needed to extend or compress a spring by some distance ( x) scales linearly with respect to that distance—that is, Fs = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness ), and x is small compared to the total possible deformation of ...

  7. Newton-Hooke priority controversy for the inverse square law

    en.wikipedia.org/wiki/Newton-Hooke_priority...

    Newton's work and claims. Newton, faced in May 1686 with Hooke's claim on the inverse square law, denied that Hooke was to be credited as author of the idea. Among the reasons, Newton recalled that the idea had been discussed with Sir Christopher Wren previous to Hooke's 1679 letter. [ 12] Newton also pointed out and acknowledged prior work of ...

  8. Newton (unit) - Wikipedia

    en.wikipedia.org/wiki/Newton_(unit)

    Imperial units. 0.224809 lbf. The newton (symbol: N) is the unit of force in the International System of Units (SI). It is defined as , the force which gives a mass of 1 kilogram an acceleration of 1 metre per second squared. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically his second law of motion .

  9. Newton's law of cooling - Wikipedia

    en.wikipedia.org/wiki/Newton's_law_of_cooling

    Newton's law of cooling. In the study of heat transfer, Newton's law of cooling is a physical law which states that the rate of heat loss of a body is directly proportional to the difference in the temperatures between the body and its environment. The law is frequently qualified to include the condition that the temperature difference is small ...
