Gravity

A galaxy's gravity can influence a planet by keeping it in orbit around a central star, like our Sun. The gravitational interactions with other celestial bodies in the galaxy can also affect a planet's orbit and trajectory over long periods of time. Additionally, the overall distribution of mass in a galaxy can influence the movement and behavior of planets within it.

Yes, gravity does affect time. According to Einstein's theory of general relativity, gravitational fields can slow down time. This effect is known as gravitational time dilation, where time runs slower in stronger gravitational fields. It has been experimentally verified, such as with atomic clocks on Earth and in space.

Gravity is caused by mass which is a property of physical matter. Even hydrogen, the lightest element in the Universe, has mass and is subject to gravity. An interesting question would be why the mass has gravity?

Yes as explained in the theory of relativity Yes. Light is affected by gravity, but because light travels so fast, the effect is not noticeable under most conditions. As light passes by something with mass its path bends toward the object in what is called gravitational lensing. We have observed this effect around massive galaxies as the light from galaxies behind them is distorted.

Gravity affects a satellite launch by pulling the satellite towards the Earth during its initial phase of ascent. This requires the rocket to generate enough thrust to overcome gravity in order to reach the desired orbit. Once the satellite is in orbit, gravity continues to affect its trajectory, helping to keep it in orbit around the Earth.

The gravitational forces between two objects act in both directions along the line

between their centers of mass.

In our daily experience, where one of the objects is always the Earth, we call one

of those directions "down" and, as relates to the forces of gravity, we ignore the

other direction completely.

Gravity is the attraction between masses. And since the moon has less mass than earth, the gravity is weaker there. Over a distance gravity is weaker.

Gravity does not directly cause day and night. Earth's rotation on its axis is what causes day and night. As Earth rotates, different parts of the planet are either facing towards the Sun (daytime) or away from the Sun (nighttime). Gravity is the force that keeps objects, including Earth, in orbit around the Sun.

Gravity is strongest near very massive objects, such as planets and stars. The strength of gravity also depends on the distance between two objects; the closer they are, the stronger the gravitational force.

Gravity is strongest in regions of space with higher mass concentrations, such as near black holes or neutron stars. Black holes have the most intense gravitational pull, creating a powerful force that can even bend light.

Mass is a property almost all matter has. It does not change from place to place, it is always constant. It is measured in Kg.

Gravity is the effect mass has on other mass. It is the effect 2 (or more) bodies of mass drawn to each other. Gravity is measured in m/(s^2), this is a unit of acceleration.

no, gravity itself is not a balanced force. it is a natural cosmic force that pull down free falling objects with a force of 9.8N/m (newtons per meter). it can however cause balanced and unbalanced forces in the fact that if you, for example, hold a pencil by its middle, gravity is acting on both sides equally based on the surface area on both sides and is therefore balancing it in air. gravity can only cause an object to fall if the object is not already attached to a resisting force or object, such as an apple on a tree, or if it is not balanced equally, as in the pencil example

An object on the moon's surface weighs 0.165 as much as it does on the Earth's surface.

Gravity is a force of attraction between objects with mass, and it does not have a distinct smell. It is a fundamental force of nature that influences the motion of objects in the universe, but it cannot be perceived through the sense of smell.

True. The gravitational force between two planets is directly proportional to the product of their masses. So, the greater the mass of a planet, the stronger its gravitational pull towards another planet.

Gravity is a natural force that exists everywhere in the universe. It is what keeps planets in orbit around the sun and objects on Earth from floating into space. Gravity is always present, whether you are on the Earth, in space, or on another celestial body.

ya it has a little bit less gravity than the moon. its........floaty..........

The gravity on Mercury is about 38% of Earth's gravity, which means that objects weigh less on Mercury compared to Earth. This is due to Mercury's smaller size and mass compared to Earth.

Neptune was discovered because of anomalies in the orbit of Uranus, indicating that another planet's gravitational pull was affecting Uranus's orbit. This led to the prediction and eventual discovery of Neptune in 1846 by Urbain Le Verrier and John Couch Adams.

In zero gravity, water forms into free-floating spheres due to surface tension. Without the downward force of gravity, water does not flatten out and instead takes on a spherical shape. This phenomenon is commonly observed in space experiments and can provide insights into fluid dynamics and surface tension behaviors.

The Wikipedia lists a gravitational acceleration of 0.003 9 m/s2. I am quite sure this is an estimate or calculation, and has never actually been measured. For comparison, Earth's gravitational acceleration is 9.8 m/s2.

A weak gravity would not be able to hold onto an atmosphere because the gas molecules would escape into space. Without an atmosphere, there would be no protection from cosmic radiation or meteoroids, making it inhospitable for life as we know it.

Really none, there is no actual planet that has the exact same gravity, some can be close, like saying it Gforce was 2000, and another was 2000, but actually its like 2000.01010203053232 and 2000.21020103020310.

Mars and Venus are roughly the same size as earth (and thus have about the same gravity), but I don't think any planet in our solar system is exactly the same as earth. Gravity is determined by mass; the planet in our solar system with a mass closest to earth is Venus.

Venus' gravity is 8.87 ms-2 whereas the Earth's gravity is 9.86 ms-2. Mars's gravity is 3.71 ms-2.

Of the eight planets that orbit the Sun, Jupiter has the strongest gravitational pull because it has more mass than any of the other planets. In fact, it has more mass than ALL the other planets combined!
