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.

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 the surface gravity on earth?
The force of gravity on the earth is 9.8 m/s^2
At what height above the earths surface would the value of acceleration due to gravity half of what it is on the surface of the earth?
The acceleration due to gravity decreases with height above the Earth's surface according to the inverse square law. Therefore, at a height of approximately 3186 km above the Earth's surface, the acceleration due to gravity would be half of what it is on the surface. This is known as the point of geosynchronous orbit.
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
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.
Why is the acceleration due to gravity on the surface of Mars is about one third the acceleration due to gravity on earths surface?
The acceleration due to gravity is lower on Mars compared to Earth because Mars has less mass than Earth, which means it exerts less gravitational pull. This difference in mass causes Mars to have a weaker gravitational field and therefore a lower acceleration due to 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.
Why does weight on an elevator change though you don't leave earths gravity?
If the elevator accelerates, the acceleration will provide an additional apparent force.
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
What is the acceleration due to gravity 9000000 meters away from the center of the earth?
If you have a known rate of acceleration and radius (such as at the earths surface), you can use the following equation to calculate the acceleration at another radius.a = k / ((d / r)^2)key:a = new acceleration rate ((m/s)/s)d = new radius (metres)k = known acceleration rate ((m/s)/s)r = known radius (metres)so if:d = 9 000 000 metresk = 9.82 (m/s)/s (acceleration at earths surface)r = 6 371 000 metres (radius at earths surface)then:a = 4.92 (m/s)/s
