And as they land, they're fully aligned in the gravitational field.

We're, of course, all stuck in the Earth's gravitational field right now.

A Gaussian surface is a closed surface in three dimensional space through which the flux of a vector field is calculated usually the gravitational field, the electric field, or magnetic field.

Gravitational Constant

Gravimetry A gravimeter or gravitometer, is an instrument used in gravimetry for measuring the local gravitational field.

Little g. So this right here, we can view that as the gravitational field at the surface of Earth.

It involves gravitational waves.

And that downward force of gravity is going to be equal to the gravitational field near the surface of the Earth

General relativity also predicts novel effects of gravity, such as gravitational waves, gravitational lensing and an effect of gravity on time known as gravitational time dilation.

We call this gravitational lensing.

Penrose suggests this extra gravitational radiation may be enough to explain the observed cosmic acceleration without appeal to a dark energy matter field.

Thus, the Earth's gravitational field (near ground level) can be quoted as 9.8 metres per second squared, or the equivalent 9.8 N kg.

And that was that the gravitational field, due to mass, will deflect not only the trajectory of particles, but will deflect light itself.

And special relativity tells us that moving clocks run slow, while general relativity tells us that clocks run faster higher in a gravitational field.

We have a go. Initiate gravitational spin.

We shift the gravitational center of it.

But as that space shuttle returns to Earth, and as the astronauts enter the Earth's gravitational field, they begin to see the effects of gravity.

But as that space shuttle returns to Earth, and as the astronauts enter the Earth's gravitational field, they begin to see the effects of gravity.

We know it's there by its gravitational effects.

That is, the system will give off gravitational waves.

They would, however, be detectable through their gravitational influence.

It's the gravitational pull that makes these things orbit.

Origin When one body (like the blue object in the diagrams at left) is in the gravitational field of a large mass (the yellow object), it becomes tidally distorted.

Stars, planets and moons retain their atmospheres by gravitational attraction.

Therefore it has a smaller gravitational pull on the astronaut.

Is that absolute, like force and mass and gravitational attraction?

These equations are used to study phenomena such as gravitational waves.

It dictates most of the gravitational forces in our solar system.

We can also include two more charges corresponding to the gravitational force.

The period of gravitational contraction lasts about 10 to 15 million years.

They're moving around in this gravitational potential well of this cluster, OK.

We shave it off, and I have a little gravitational lens, OK.

Sometimes this is also viewed as the gravitational field at the surface of the Earth, because if you it multiply by mass it tells you how much force is pulling on that mass.

The gradient of this potential also provides a model of the gravitational acceleration.

Minus 200 in the shade. Canyons of razor sharp rock. Unpredictable gravitational conditions.

But we'll assume no gravitational interaction, absolutely no particles that it's bumping into.

The gravitational pull of things was a lot stronger near the Big Bang.

The L2 point provides the spacecraft with a very stable gravitational and thermal environment.

So clusters of galaxies will tend to form, because of all this gravitational attraction.

In physics, gravitational acceleration is the acceleration on an object caused by force of gravitation.

So what we can do with it is we shift the gravitational center of it.

F G x M1 x M2 R 2, where G is the universal gravitational constant,

Physicists believe that rope is the gravitational force from stuff we can't see Hence, Dark Matter.

A possible cause of such a warp could be gravitational interaction with the satellite galaxies near M31.

The Virgo cluster lies within the Virgo Supercluster, and its gravitational effect slows down the nearby galaxies.
