- Then the accretion efficiency, or the fraction of energy actually radiated of that theoretically available from the gravitational energy release of accreting material, enters in an essential way.
- Perhaps, the researchers theorized, the channels etched in the landscape over the centuries formed patterns that allowed water to dissipate the least possible gravitational energy on its way downhill.
- Translating the above statement into the language of general relativity, we say that a system in nearly flat space-time has a total non-gravitational energy E and momentum P given by:
- The coupling of a universal scalar field directly to the gravitational field gives rise to potentially observable effects for the motion of matter configurations to which gravitational energy contributes significantly.
- No, because the vacuum fluctuation that created the particles was in effect a defect in space that " borrowed " energy from the black hole's mass-energy ( or gravitational energy ).
- In the 1930s, Pascual Jordan knew that a star could equal zero energy because its matter energy was positive and its gravitational energy was negative and they cancelled each other out.
- This is the same as the calculations of potential gravitational energy in classical mechanics ( of course, the nature of the force is different ), and should be enough to explain the released energy.
- The negative value for gravitational energy also has deeper implications that make it seem more reasonable in cosmological calculations where the total energy of the universe can meaningfully be considered; see inflation theory for more on this.
- An eighth grade science teacher at the Horace Mann School said she would eliminate a test question this year that asks students to calculate the potential gravitational energy of a tightrope walker between the World Trade Center towers.
- What this means is that the continuity equation no longer implies that the non-gravitational energy and momentum expressed by the tensor are absolutely conserved, i . e . the gravitational field can do work on matter and vice versa.
- If a cloud begins to contract because of its own gravity, its interior heats up as gravitational energy is converted to heat energy, reaching millions of degrees, and nuclear reactions begin that change one element into another, releasing energy.
- After reading that discussion again though, it's possible that the mass of the singularity might exceed the mass of the matter that was actually compressed because the gravitational energy of the matter adds to the mass of the singularity.
- In youth a brown dwarf may glow hot from the gravitational energy of the compressing interstellar gases, but if critical mass is not reached and fusion begun, in time it will cool off, leaving a dim glow from residual gravitational energy.
- In youth a brown dwarf may glow hot from the gravitational energy of the compressing interstellar gases, but if critical mass is not reached and fusion begun, in time it will cool off, leaving a dim glow from residual gravitational energy.
- Its voyage to the Sun began with a sixteen month trip to Jupiter where the planet's gravitational energy was used to fling Ulysses southward out of the orbital plane of the planets and on toward a solar south pole passage in 1994.
- Now, we know that for gravitational energy, E = mgh, so when I'm winding it up, I'm providing about 30 Joules of energy over 15 seconds of work-so I'm providing about 2 Joules / second or 2 Watts while I'm cranking it.
- He described how all the mass energy which is positive and all the gravitational energy which is negative cancel each other out leaving us with a universe with zero energy . That is how the universe could have begun from zero energy, nothing.
- The earth's core is theorized to be a solid, mostly iron, crystal that is extremely hot, due in part to the enormous pressure that it is under from the gravitational energy of all the mass of the planet pushing in to the center.
- At the very end of this process, the two objects will reach extreme velocities, and in the final fraction of a second of their merger a substantial amount of their mass would theoretically be converted into gravitational energy, and travel outward as gravitational waves,
- In its final moments of spiraling inward and merging, GW150914 released around 3 solar masses as gravitational energy, peaking at a rate of 3.6 watts more than the combined power of all light radiated by all the stars in the observable universe put together.
