The force of gravity causes all objects near the earth's surface to fall with exactly 9.80665 m/s2 (approx. 32.174 ft/s2). The statement in the question is accurate except for the actual magnitude of the earth's gravitational constant. The earth's gravitational constant g (or go or gn) is 9.80665 meters per second squared per international agreement. A link is provided to the Wikipedia article with the figure stated along with particulars and other related links.
no,it is not twenty.the force of acceleration causes all objects near the surface of te earth to fall with an acceleration of 9.8m/s.This is however an average value ,this may change from place to place by a small value.
9.8 meters (32.1 feet) per second per second.

The acceleration of gravity at the surface of Mars is approximately 3.7 m/s2. Earth's acceleration is 9.8 m/s2 on average. The force that gravity would exert on an object is dependent on its mass.
Wow. That is one of the great unanswered questions of Physics. Nobody knows how gravity works. People have, over the centuries, formulated natural laws that describe the behavior of objects under the influence of gravity; Galileo Galilei, Issac Newton, and Albert Einstein for example.Look it up on wikipedia. Go to http://en.wikipedia.org/, and search for Gravity.
The acceleration of gravity at the surface of the Earth is 9.81 meters per second2 . That means that the downward force on any object at the surface is 9.81 newtons per kilogram of mass.
-- The rate of acceleration of an object on the moon is(the net force on the object)/(the object's mass) .-- If the object is falling, with nothing but the force of gravity acting on it, thenits acceleration is 1.623 m/s2 (compared to 9.807 on Earth).
The magnitude of acceleration due to gravity depends on the mass of the object toward which you're attracted by gravity, and on your distance from it. There are trillions of different possibilities in space.
weight
In free fall,the force of gravity alone causes an object to accelerate in downward direction Huizar,Alexandra
The acceleration affects the weight of the person and object
The acceleration of gravity ... and therefor the weight of any object ... on thesurface of Mercury is 37.698% of its value on the surface of Earth. (rounded)
The force of gravity on a person or object at the surface of a planet is calculated by the product of the mass of the person or object and the gravitational constant acceleration for the planet. For Earth, the gravitational acceleration is 9.8 m / s^2.
On the surface of Venus, the acceleration of gravity, and therefore the weight of any object, is 90.3 percent of what it is on the surface of Earth.
At or near the surface of the earth, the acceleration due to gravity is 32 feet per second per second
Weight The force of gravity on an object is its weight. If we know the mass of the object, and the acceleration due to gravity we can calculate the weight of an object as follows weight= mass x acceleration due to gravity W=mg Units : newtons (because weight is a force) Example: Given an object on the surface of the earth Mass of the object=1 kg acceleration due to gravity on the surface of the earth is approximately 9.8m/s2 -->W=mg=1x9.8=9.8 newtons
-- In a reference book or on-line, look up the acceleration of gravity on the surface of that planet. -- Multiply the mass of the object by the acceleration of gravity in the place where the object is. The result is the object's weight in that place.
Object's weight = (object's mass) multiplied by (acceleration of gravity in the place where the object is)
The acceleration of an object due to gravity does not depend on the mass. Close to Earth's surface, this acceleration is about 9.8 meters per second per second.
The acceleration of gravity on the surface of Mars, and therefore the weightof any object placed there, is 37.95% of its value on the Earth's surface.
