... loses kinetic energy with distance increase. Furthermore blood flowing from the lower limbs back to heart through the inferior vena cava is aginst gravitational pull. thats why vena cava, veins all have semi lunar valve to prevent backflow of blood.

... coupled scalar field with a potential that decreases as the field increases is usually introduced for this purpose . The action is given bythe 4D gravitational constant. This is a canonically normalized scalar action coupled to the 4D gravity.for cosmological purpose, then the energy density and ...

The effect that they describe and that could be discovered by LIGO (Laser Interferometer Gravitational-Wave Observatory), a facility for detecting gravitational waves that is just becoming operational, could provide support for string theory ...

... of it is still present as a component of the modern atmosphere. B) When the Earth melted, it burned. C) It escaped into space because the Earth's gravitational field was not strong enough to hold it. D) Most of it combined with the oxygen in the early atmosphere to form water, which rained down ...

... down. THEREFORE IF IT'S FLOATING AROUND, IT HAS POTENTIAL, RIGHT? I don't really understand what she meant by this: maybe potential energy in a gravitational field where something is considered to have potential energy if they can convert it into kynetic energy by falling. We are discussing ...
