Gravitational Forces facts

While investigating facts about Gravitational Forces Definition and Gravitational Forces Examples, I found out little known, but curios details like:

We actually have photographs showing entire star systems being warped in space-time by immense gravitational force. These Gravitational Lenses appear to us a circular bubble of stars and galaxies, and prove Einstein's Theory of General Relativity.

how are electrical and gravitational forces similar?

Earth is being shadowed by a minor planet called 2010 TK7, a 300 meter diameter trojan asteroid that orbits the sun in a spiral pattern every 365.3 days, 60° ahead of Earth's track through space. It has a gravitational force 1/20000 that of Earth and was only discovered in 2010.

What two forces are balanced in gravitational equilibrium?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what is a result of gravitational forces in the solar system. Here are 23 of the best facts about Gravitational Forces Between Two Masses and Gravitational Forces Worksheet I managed to collect.

what are gravitational forces?

1. Earth's crust under the Solar Eclipse of Aug 21 will rise about 40 millimeters, due to the combined gravitational force of the Sun and the Moon.

2. The ratio of the speed of light multiplied by the age of the universe, to the classical electron radius, is the same order of magnitude as the ratio of the electrical to the gravitational forces between a proton and an electron

3. The temperature of the inner core is believed to be approximately 5400 degrees Celsius, or 5700 Kelvin. This heat is caused by three elements: residual heat from the formation of the earth, gravitational forces from the moon and the sun, and and radioactive decay of earth's inner elements.

4. The moon's gravitational force is only one tenth-million of the earth's gravitational force. But other factors such as the earth's spin and resulting centrifugal force, contribute to tides.

5. While astronauts feel weightless, Earth's gravitational force is only 10% less in a spaceship orbiting Earth.

6. Despite the moon's gravitational force being so much less than the earth's gravitational force, it is the most important factor in the creation of tides on earth. This is because the sun's gravitational force is even less than the moon's gravitational force (at only 46% of the moon's force).

7. Gravitational force responsible for tides is referred to as "tractive force".

8. Maximal tides are caused when the moon, earth, and sun are aligned as the sun's gravitational force adds to the moon's gravitational force at these times.

9. Your body weight at the center of the earth would be zero as all the gravitational forces would be pushing on you equally from all points.

10. The gravitational force of a neutron star is such that if you fall from a height of one meter (3 feet), you would hit the ground at around 2000 kilometers per second, or 7.2 million kilometers per hour.

Why are gravitational forces defined as negative?

You can easily fact check why does gravitational force exist by examining the linked well-known sources.

The L5 Society wants to put space stations at points in space that are stationary due to equilibrium of gravitational forces.

"spring tides" which are very drastic due to the combined effects of the gravitational force of the Moon and the Sun on Earth occur during solar eclipses - source

Centrifugal force from the Earth's rotation counteracts gravitational pull by up to 0.3% - source

Astronauts are not in zero-gravity, but are instead in free fall around Earth. Zero gravity means the absence of gravitational forces, which doesn't exist.

The US Navy has recently patented several radical aviation technologies including designs for a high frequency gravitational wave generator, a room temperature superconductor, an electromagnetic force field generator, and an inertial mass reduction device - source

When gravitational forces and air resistance equalize?

Lagrange points where small objects/satellites/spacecraft such as SOHO can orbit in space, without orbiting around a planet such as Earth. These points occur where the gravitational pull of two large masses precisely equals the centripetal force required for a small object to move with them.

How are gravitational and electromagnetic forces alike?

Scientists are examining data from an astonishing cigar-shaped "interstellar object" they named Oumuamua ("Messenger"), which recently buzzed through our solar system. It traveled in a highly improbable pathway, using the sun's gravitational force to accelerate its trajectory.

Tides are caused by the combined effects of gravitational forces exerted by the Moon, Sun, and rotation of the Earth

When a star becomes black hole there is no increase in gravitational force at a distance equal to the radius of the star from which black hole was formed.

For a 70 kg/ 154 lbs human to balance the Earth on a lever, he/ she would have to stand 18 million light years away (given a uniform gravitational force)

Astronauts on the ISS are actually under about 90% of the gravitational force we are on earth. They only 'appear' to be weightless because they're actually in a constant state of free fall.
