Meaning of law in Science

Meaning of law in Science

The test of any scientific law is our verification of its anticipations. A people, superstitious and ignorant of every scientific law, wondered to see Him do what He did. The scientific law of atavism is a guarantee of resurrection. In defining our problem, therefore, we find ourselves under the influence…

Formula for universal Gravitation

Formula for universal Gravitation

Fg = force due to gravity between the two objects (N) G = the Gravitational Constant m1 and m2 = the two masses (kg) r = the distance between the two objects’ centres (m) This formula shows that any objects with mass will pull towards each other with a gravitational force. You might have heard the phrase…

Gravitational pull on Earth

Gravitational pull on Earth

Where G if Newton s gravitational constant, is the mass of the object being pulled on by the Moon, MMoon is the mass of the Moon, and rMoon is the distance between the Moon and the object. A similar force acts between the Earth and various objects, except that we use the distance to the Earth, rEarth…

Gravitational constant value

Gravitational constant value

NIST has taken part in a new push to address a persistent and growing problem in physics: the value of G. The Newtonian constant of gravitation, used to calculate the attractive force of gravity between objects, is more than 300 years old. But although scientists have been trying to measure its value…

Dark energy NASA

Dark energy NASA

How does the universe work? Understanding the universe s birth and its ultimate fate are essential first steps to unveil the mechanisms of how it works. This, in turn, requires knowledge of its history, which started with the Big Bang. Previous NASA investigations with the Cosmic Microwave Background…

Discovery of Dark energy

Discovery of Dark energy

In 1998, two teams of astronomers discovered that, instead of slowing down, the universe is expanding faster today than it was in earlier epochs Adam Riess Adam Riess thought there must have been a mistake. In late 1997, he was analyzing observations of exploding stars to help determine whether the universe…

Universal of Gravitation

Universal of Gravitation

Physics is based on the assumption that certain fundamental features of nature are constant. Some constants are considered to be more fundamental than others, including the velocity of light c and the Universal Gravitational Constant, known to physicists as Big G. Unlike the constants of mathematics…
