Earth's gravity is what keeps you on the ground and what makes things fall. Anything that has mass also has gravity. ... You exert the same gravitational force on Earth that it does on you. But because Earth is so much more massive than you, your force doesn't really have an effect on our planet.View full answer
Beside the above, What exerts a gravitational force?
Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of the objects. You exert a gravitational force on the people around you, but that force isn't very strong, since people aren't very massive.
Also, Is the force that the earth exerts?. Gravitational force or commonly called gravity is the force the planet Earth exerts on any object located on its surface or located far away from its surface.
Besides, Does Earth exert a gravitational force on the sun?
All objects attract one another, including Earth and the Sun. The force of this attraction—or gravitational pull—depends on the size of the objects. As the Sun is very large, it exerts a great gravitational force on Earth. ... This means that the planet neither flies out into space nor falls into the Sun.
Where is gravity strongest on Earth?
In the case of the earth, the force of gravity is greatest on its surface and gradually decreases as you move away from its centre (as a square of the distance between the object and the center of the Earth). Of course, the earth is not a uniform sphere so the gravitational field around it is not uniform.
Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location.
The Sun Has a Lot of Pull!
The Sun's gravity is about 27.9 times that of Earth, and, in a small way, it helps to control the tides on Earth.

Our Sun – the heart of our solar system – is a yellow dwarf star, a hot ball of glowing gases. Its gravity holds the solar system together, keeping everything from the biggest planets to the smallest particles of debris in its orbit.
The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall.
Moon has a surface gravity 17% of the Earth's, but its gravitational force is strong enough to keep the Earth from changing its orbital tilt drastically.
What do you feel when you hold it against the pull of gravity. Force is what you feel when you shake something too and fro. The amount of mass is the same no matter where you shake it.
Isaac Newton: The man who discovered gravity.
We all know that all the forces in nature exist in opposites, but gravitational force is the only force that always attracts every object and never reples any.
Essentially, gravity holds our world together. ... In addition, gravity is weaker at the equator because of centrifugal forces produced by the planet's rotation. Gravity is also a bit weaker at higher altitudes, being farther from Earth's center, such as the summit of Mount Everest.
gravity increases with height. gravity is significantly less on high mountains or tall buildings and increases as we lose height (which is why falling objects speed up) ... gravity affects things while they are falling but stops when they reach the ground. It does not operate on things that are moving upwards.
Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system's hottest planet. The average temperatures of planets in our solar system are: Mercury - 800°F (430°C) during the day, -290°F (-180°C) at night. Venus - 880°F (471°C)
The biggest: UY Scuti
One day, the Sun will become a red giant. But if it had started its life with a dozen or so times its current mass, it could have eventually evolved into a red supergiant. (UY Scuti has already shed a lot of mass.)
At 12.7 billion years old, planet Psr B1620-26 B is almost three times the age of Earth, which formed some 4.5 billion years ago. This exoplanet, the oldest ever detected in our Milky Way galaxy, has been nicknamed “Methuselah” or the “Genesis planet” on account of its extreme old age.
The sun and moon are not planets when you consider the objects in space they orbit. For the sun to be a planet, it would have to orbit another sun. Although the sun is in a orbit, it moves around the center of mass of the Milky Way galaxy, not another star.
A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. ... In many ways, a black hole acts like an ideal black body, as it reflects no light.
G is the universal gravitational constant, G = 6.674 x 10-11 m3 kg-1 s-2. M is the mass of the body measured using kg.
G is called Universal Gravitation Constant because its value i.e. 6.67 x 10-11 Nm2kg-2 is constant thought the universe.
Note: The acceleration due to gravity is maximum at poles because the poles are near to the centre of mass of the earth. And the equator is somewhere far away from the centre of mass of the earth.
