Law of Gravitation Physics
Gravity is the weakest of the four fundamental forces, yet it is the dominant force in the universe for shaping the large scale structure of galaxies, stars, etc. The gravitational force between two masses m1 and m2 is given by the relationship: This is often called the universal law of gravitation and G the universal gravitation constant. It is an example of an inverse square…

Gravitational constant of the Earth
The Controversy over Newton s Gravitational Constant In 1686 Isaac Newton realized that the motion of the planets and the moon as well as that of a falling apple could be explained by his Law of Universal Gravitation, which states that any two objects attract each other with a force equal to the product of their masses divided by the square of their separation times a constant…

Gravitational pull of Sun
What is the gravational pull of the sun? - forman (age 15) north shore, california A: Well, the strength of a gravitational field of a spherically symmetrical object is inversely proportional to the square of the distance you are from the center (that is, if you are outside - I hope you re outside of the sun!). So your answer depends on where you are. If you re standing on…

What is the relativity theory?
Relativity is one of the most famous scientific theories of the 20th century, but how well does it explain the things we see in our daily lives? Formulated by Albert Einstein in 1905, the theory of relativity is the notion that the laws of physics are the same everywhere. The theory explains the behavior of objects in space and time, and it can be used to predict everything…

Formula for force of attraction
Field of a cylindrical bar magnet calculated with Ampère s model Two models are used to calculate the magnetic fields of and the forces between magnets. The physically correct method is called the Ampère model while the easier model to use is often the Gilbert model. Ampère model: In the Ampère model, all magnetization is due to the effect of microscopic, or atomic, circular…
