The gravity of Earth, denoted g, refers to the acceleration that the Earth imparts to objects on or near its surface. In SI units this acceleration is measured in metres per second per second (in symbols, m/s2 or m·s-2) or equivalently in newtons per kilogram (N/kg or N·kg-1). It has an approximate value of 9.81 m/s2, which means that, ignoring the effects of air resistance, the speed of an object falling freely near the Earth's surface will increase by about 9.81 metres (about 32 ft) per second every second. This quantity is sometimes referred to informally as little g (in contrast, the gravitational constant G is referred to as big G).There is a direct relationship between gravitational acceleration and the downwards weight force experienced by objects on Earth, given by the equation F = ma (force = mass × acceleration). However, other factors such as the rotation of the Earth also contribute to the net acceleration.Although the precise strength of Earth's gravity varies depending on location, the nominal "average" value at the Earth's surface, known as standard gravity is, by definition, 9.80665 m/s2 (32.1740 ft/s2). This quantity is denoted variously as gn, ge (though this sometimes means the normal equatorial value on Earth, 9.78033 m/s2), g0, gee, or simply g (which is also used for the variable local value). The symbol g should not be confused with g, the abbreviation for gram (which is not italicized).

How is the moon held in its orbit round the earth?

The moon is held in its orbit around the Earth by gravitational forces. The gravitational pull of the Earth keeps the moon in its orbit, while the moon's own motion and inertia prevent it from falling into the Earth. This delicate balance of forces results in the moon continuously orbiting the Earth.


Would an object have a greater gravitational pull closer or farther from earth?

An object have greater gravitational pull closer from earth. As we get farther from earth, the gravitational pull becomes weaker. That is why objects sufficiently away from the earth do not fall on it.


How strong is the earths moons gravatational pull?

The gravitational pull of Earth's moon is about 1/6th that of Earth. This pull is what causes tides on Earth and keeps the moon in orbit around our planet. It also affects the Earth's rotation and the tilt of its axis.


What causes a bulge to be created on the opposite side of the moon?

The gravitational pull of the earth causes a bulge on the opposite side of the moon. The gravitational pull of the earth is greater than the gravitational pull of the sun.


Why do things move towards the Earth but not toward people?

Because the gravitational pull of the Earth is much larger than the gravitational pull of lets say... a human. You could argue that on earth there is a gravitational pull to humans, but the Earth is over powering that pull. So the object is pulled down (to the surface of the Earth) rather than to you or me.

Is the pull of gravity between the moon and the earth keeps the moon orbiting the earth?

Yes, the gravitational pull between the Earth and the Moon is what keeps the Moon in orbit around the Earth. This gravitational force is what causes the Moon to travel in a curved path around the Earth rather than moving off into space.
