How would the acceleration of gravity near earths surface change?

In general, when near the Earth's surface, scientists use 9.8 meters per seond^2 since the slight difference in elevation along the Earth's surface doesn't affect the acceleration very much. But if you want the exact formula it is: (G(msub1)(msub2))/radius^2. msub1 and msub2 are the masses of the two objects, and G is 6.67x10^(-11), the gravitational constant.

∙ 13y agoIt would vary depending on distance from the surface and the density of the matter under the surface.

∙ 14y agoDue to evolution, most species would become smaller, so they could move properly if the gravitation rised, and got bigger, if the gravitation falled.

How strong is mars gravity compared to earths?
The acceleration of gravity on the surface of Mars is 3.722 m/s2 .That's about 38 percent of its value on Earth.
After a shuttle is launched into orbit what happens to gravity?
There is no gravity in space but the shuttle stays in orbit because of the Earths gravity and inertia. The inertia keeps it going in a circular motion. In space the Earth's gravity is strong enough to hold something in orbit but not strong enough to pull it to Earth's surface.
Explain why free fall acceleration near earths surface is constant?
Since the radius of Earth is far greater(rough: 6400km) than a few 100m, you can neglect that distance and still have g=9.80 (g=GM/(R^2), with R being the radius of earth, a few 100m dont do much difference in g's equation)
Which force is responsible for tides in the sea?
The "force" your talking about is the moons gravity as well as the suns gravity for example a "spring tide" is when the moon and sun are on opposite sides of the earth therefor stretching the oceans into an oval. A spring tide is the optimal tide meaning it is the strongest type of tide but only occurs roughly every month
Most minerals on earths surface contain which of the following?
silicon & oxygen.
What is makemakes gravity compared to earths gravity?
The acceleration of gravity at its surface is currently estimated as 0.4 m/s2 .That's about 4% of the acceleration of gravity on the Earth's surface.
What is the surface gravity on earth?
The force of gravity on the earth is 9.8 m/s^2
Why is the acceleration due to gravity on the surface of Mars is about one third the acceleration due to gravity on earths surface?
Because the acceleration of gravity on the surface of any given body depends on the mass of the body and its radius ... the distance of the surface from the center. Mars' mass ... about 11% of Earth's ... and Mars' radius ... about 53% of Earth's ... combine to produce about 38% of Earth's gravitational acceleration at the surface of Mars.
What is the compare of the earth and the moon in terms of size and surface gravity?
earth is 81.3 times the mass of the moon . acceleration due to gravity at earths surface = 9.82 (m/s)/s acceleration due to gravity at moons surface = 1.62 (m/s)/s . 1 kg at earths surface, force = 1 * 9.82 = 9.82 newtons 1 kg at moons surface, force = 1 * 1.62 = 1.62 newtons
When you push UP on an object when object is stationary on earths surface you increase your weight when you push DOWN on an object when object is stationary on earths surface you decrease your weight?
No, your weight is just the acceleration due to the Earth's gravity,
Why does the acceleration of gravity vary from one point to another on the earths surface?
Different air pressure, so there is more/less air resistance.
Why is acceleration due to gravity the same for all objets?
because all are measured at the same radius from the earths cog, if you doubled this distance, the acceleration would be only one quarter that of the surface
Where do you experience more gravity on earths surface or earths center?
on the surfaceNote:Since the earth's composition is not homogeneous, the gravitational acceleration onthe surface is probably less than what it is some small distance below the surface,but it's certainly greater than at the center.
What is the Suns gravity in relation to Earths gravity?
The Sun's gravity, at its surface, is about 28 times Earth's surface gravity.
How much more is Earths surface of gravity than the Moon's?
Earths surface of gravity is 4.6m/s2 more than moons.
How is gravity affected if mass is changed?
if you double the earths density say , standing at the surface you would experience twice the acceleration, weight would be doubled
Which planets surface gravity is 38 percent that of earths?
Both mercury and mars have a gravity which is around 38% of earths. Mercury's gravity is 37.8% of earths, Mars' gravity is 37.7% of earths.
