Newton's Law of Gravitational Attraction

Das Newtonsche Gesetz der Gravitationsanziehung besagt, dass, wenn zwei Teilchen der Massen m1 und m2 durch die Entfernung r getrennt sind, sie sich gegenseitig mit gleichen und entgegengesetzten Kräften anziehen.
Die Anziehungskraft wirkt entlang der Linie, die die Teilchen verbindet, und variiert direkt als Produkt ihrer Massen und umgekehrt als Quadrat des Abstands zwischen ihnen, wobei G die universelle Konstante ist, die als Gravitationskonstante bekannt ist.
Die Anziehungskraft, die die Erde auf ein Objekt ausübt, ist das Gewicht des Objekts. Es ist das Produkt aus der Masse des Objekts und der Beschleunigung aufgrund der Schwerkraft, ausgedrückt in Newton.
Schwerkraftabscheider, Fallhämmer und Schwerkraftförderer sind einige mechanische Werkzeuge, die nach dem Prinzip des Newtonschen Gravitationsgesetzes arbeiten.
Betrachten Sie den Fallhammer-Schmiedeprozess. Dabei wird der Hammer mit einem bestimmten Gewicht auf eine bestimmte Höhe angehoben und dann frei fallen gelassen.
Da die Erde eine starke Anziehungskraft hat, fällt der Hammer immer. Die durch diesen Sturz erzeugte Kraft gibt den Werkstücken die gewünschte Form.

das gesetz der gravitationsanziehung von newton

Sir Isaac Newton begründete die Allgemeingültigkeit des Gesetzes der Gravitationsanziehung auf der Grundlage empirischer Beweise und induktiver Argumentation. Er veröffentlichte seine Arbeit in „Philosophiae Naturalis Principia Mathematica“ („the Principia“) am 5. Juli 1687. Das Gesetz der Gravitationsanziehung von Newton ist ein grundlegendes physikalisches Gesetz, das die Anziehung zwischen Objekten regelt. Es besagt, dass die Stärke der Gravitationskraft zwischen zwei Objekten proportional zu ihren Massen und umgekehrt proportional zum Quadrat ihres Abstands voneinander ist. Die Gravitation ist stärker zwischen Objekten mit größerer Masse. Jedes Paar von Körpern erfährt gravitationsbedingte Kräfte. Eine der weit verbreitetsten Anwendungen dieses Gesetzes ist unser Verständnis für die Bewegung der Planeten im Sonnensystem. Die Gravitationskraft zwischen den Planeten und der Sonne ist für ihre Bewegung um die Sonne verantwortlich. Es erklärt auch Phänomene wie Gezeiten, die durch die gravitationsbedingte Kraft des Mondes auf die Erde verursacht werden. Ein weiteres Beispiel, bei dem dieses Gesetz verwendet wird, ist der Entwurf von Achterbahnen. Die Wagen von Achterbahnen werden mit einem Kettenlift in Bewegung gesetzt, der die anfängliche Kraft zum Hochfahren des Wagens auf den ersten steilen Hügel bereitstellt. Oben angekommen, zieht die Schwerkraft den Wagen durch eine Reihe von Kurven, Schleifen und Abfahrten auf der Strecke nach unten. Das universelle Gesetz der Gravitation ist bedeutsam, weil es erfolgreich viele Phänomene erklärt hat, wie zum Beispiel wie verschiedene Objekte im makroskopischen Universum sich gegenseitig beeinflussen, wie die Schwerkraft für das Gewicht eines Körpers verantwortlich ist und uns auf dem Boden hält, wie der Mond um die Erde kreist, wie planetare Bewegungen stattfinden, die Entstehung von Gezeitenkräften und so weiter.

gravity between masses and distance

Newton’s law of gravitational attraction describes how gravity acts between two objects. Sir Isaac Newton built this law from empirical evidence and inductive reasoning. He published it in Philosophiae Naturalis Principia Mathematica, or the Principia, on July 5, 1687.

The law says that the gravitational force between any two objects depends on their masses and their distance apart. The force is proportional to mass and inversely proportional to the square of the distance between the objects. In simple terms, larger masses create stronger gravity, while greater distance weakens the force.

Every pair of bodies experiences gravitational force. This law helps explain the motion of the planets in the solar system. The pull between the Sun and the planets keeps them moving around the Sun.

Newton’s law also explains tides on Earth. The Moon’s gravitational force on Earth produces tidal forces. The same idea helps describe roller coasters, too. A chain lift hill gives the cart its initial motion up the first steep hill, and then gravity pulls it down through turns, loops, and drops.

This universal law of gravitation is important because it explains many large-scale effects in the macroscopic universe. It accounts for a body’s weight and helps keep us on the ground. It also describes the Moon’s motion around Earth, planetary motion, and the generation of tides.

Gravity Between Masses and Distance

an introduction to mechanics

Mechanics in Physics and Engineering

Mechanics is a key branch of physics that explains how objects stay at rest or move when forces act on them. It also has major uses in engineering and science. The topic helps students understand everyday motion, machine behavior, and the way many systems work. The recorded history of mechanics begins with Aristotle, who lived from 384 to 322 BC. He linked mechanics with physical theory and looked for a broad universal explanation. Later, Newton defined mechanics as the study of objects at...

basic concept

Fundamental Quantities in Engineering Mechanics

Engineering mechanics begins with four basic quantities: length, time, mass, and force. These ideas help describe how objects move and how they respond to loads. They also support many other engineering fields. Length measures the distance traveled by an object. Engineers describe this distance with coordinates relative to a reference point. Length is also useful for showing the geometry of physical systems. Time measures the succession of an event. A bus traveling from city X to city Y is a...

newton's law of motion

Newton's Laws and Everyday Motion

Newton's laws explain everyday motion and the forces that change it. These three laws describe why objects move, stay still, or speed up. They also show how force and mass affect motion. Newton's first law is the law of inertia. It says an object at rest stays at rest, and an object in motion keeps moving at a constant speed and direction unless an external force acts on it. A sliding box that slows down on its own is a good example. In that case, friction is the net external force that works...

units of measurement

SI and Customary Measurement Systems

Mechanical engineering depends on units of measurement for precise and accurate calculations. These units give engineers a standard way to express and compare physical quantities. They are essential when designing and analyzing machines and mechanical systems. Many historical measurement systems have been used over time. Examples include the Babylonian system, the Roman system, the Egyptian system, the Olympian system, the British system, and the Indus Valley system. Today, the International...

international system of units

SI Units and Metric Prefixes

SI units and metric prefixes provide a standard way to measure size, mass, and time. The International System of Units, or SI system, is used worldwide because it gives scientists a common language for measurement. Its values do not change with location, which helps keep results consistent. The SI system is built on three base units: meter, kilogram, and second. These are the core units for length, mass, and time. The kilogram is the only base unit that already includes a prefix. Prefixes...

numerical calculations

Engineering Notation and Significant Figures

Numerical calculations in engineering depend on clear values, correct units, and careful rounding. Presenting the answer is an important part of engineering practice, so numerically accurate results are preferred. Handheld calculators and computers are often used because they help produce accurate answers. Problems can be solved in several ways. Solving algebraic symbols by hand is common, and the graphical method is often preferred in some cases. Computers are especially useful when many...

accuracy, limits, and approximation

Accuracy and Approximation in Calculations

Accuracy and approximation are important in calculations, especially in engineering. Accuracy means how close a measured value is to the true or actual value. Repeated measurements are often used in engineering mechanics to help make results more precise and accurate. The accuracy of a solution depends on empirical data and the results from different calculations or measurements. A cylindrical container filled with liquid is a simple example. Its volume can be found from the measured...

dimensional analysis

Using Dimensions to Check Physics Equations

Dimensional analysis is a useful way to check physics and engineering equations. It works by writing physical quantities in terms of basic dimensions such as mass, length, and time. Quantities like velocity, acceleration, and force are derived from these basic dimensions. This method helps compare measurements even when the units are different. It also checks whether an equation is dimensionally homogeneous. That means the powers of the fundamental dimensions must match on both sides of the...

problem solving in statics

Statics Problem-Solving Steps for Beams

Statics problem-solving uses a step-by-step method to analyze bodies in equilibrium, especially beams. It is an important part of physics and engineering because the goal is to find practical and accurate answers for real situations. The process usually starts with a physical situation and then turns it into a mathematical model. That model often needs approximations and assumptions. Very small distances can be ignored when they are much smaller than the main dimensions, such as beam width...

Develop a model based on evidence to illustrate the life span of the sun and the role of nuclear fusion in the sun's core to release energy that eventually reaches Earth in the form of radiation.  Emphasis is on the energy transfer mechanisms that allow energy from nuclear fusion in the sun's core to reach Earth. Examples of evidence for the model include observations of the masses and lifetimes of other stars, as well as the ways that the sun's radiation varies due to sudden solar flares ("space weather"), the 11-year sunspot cycle, and non-cyclic variations over centuries .
