For points inside a spherically symmetric distribution of matter, Newton's shell theorem can be used to find the gravitational force. The theorem tells us how different parts of the mass distribution affect the gravitational force measured at a point located a distance r 0 from the center of the mass distribution: [13]
The gravitational field of a spherically symmetric mass distribution like a mass point, a spherical shell or a homogeneous sphere must also be spherically symmetric. If n ^ {\displaystyle {\hat {\mathbf {n} }}} is a unit vector in the direction from the point of symmetry to another point the gravitational field at this other point must therefore be
An irregular distribution of matter is therefore unstable under the influence of gravity, becoming more and more irregular as time goes by. This instability is exactly what is needed to explain the observation that the Universe is much more irregular now than at decoupling, and gravitational instability is almost universally accepted to be the ...
is the gravitational constant; is the mass under consideration; is the mass of each star in the star distribution; is the velocity of the object under consideration, in a frame where the center of gravity of the matter field is initially at rest
The net result is that an object at the Equator experiences a weaker gravitational pull than an object on one of the poles. In combination, the equatorial bulge and the effects of the surface centrifugal force due to rotation mean that sea-level gravity increases from about 9.780 m/s 2 at the Equator to about 9.832 m/s 2 at the poles, so an ...
Now, Doritos has finally made snacking in the stars possible with a new chip made for space. Doritos' limited-edition "Doritos minis Cool Ranch Zero Gravity flavored tortilla chips" are designed ...
Due to centrifugal force, matter tends towards the outer edges of the vortex, which causes a condensation of this matter there. The rough matter cannot follow this movement due to its greater inertia—so due to the pressure of the condensed outer matter those parts will be pushed into the center of the vortex. According to Descartes, this ...
The final logo would illustrate the “Gravitational Pull of Pepsi.” “The Pepsi ethos has evolved over time,” the document said. “The vocabulary of truth and simplicity is a reoccurring ...
