#### Gravitational force video

Dropping things can be fun. Dropping things in a vacuum is even cooler. You might think that dropping things in a giant vacuum chamber would be the ultimate in coolness. Well, it’s close. In fact, this is the best feather and heavy object dropping video. Yes, astronaut David Scott dropped a hammer and…

#### 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

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

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, and the mass of the Earth, MEarth, in place of the lunar values. Since the…

#### 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 for centuries, G is still only known to 3 significant figures. By contrast…

#### 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 Explorer (COBE) and the Wilkinson Microwave Anisotropy Probe (WMAP) have measured…
