What is the force experienced due to the Earth's gravitational pull?

Answer 1

On the surface (or near it!) it's 9.81m per second squared. More generally it's; a=f/m1, and f=Gm1m2/r2 where; a = acceleration

f = force

m1 = mass 1 (ie falling body)

m2 = mass 2 (ie attracting planet)

G = gravitational constant = 6.67300 × 10-11 m3 kg-1 s-2

r2 = distance from centre of m2 to falling body (m1) squared (ir radius squared)

Answer 2

The force experienced due to the Earth's gravitational pull is known as weight. It is the force with which an object is pulled toward the center of the Earth. The weight of an object is equal to the mass of the object multiplied by the acceleration due to gravity (9.81 m/s^2).

Answer 3

The acceleration of gravity is 32 feet per second per second, or 9.8 meters per second per second.

So, an item dropped from a tall building will fall 16 feet in the first second (accelerating from zero to 32 feet per second), and 48 feet in the next second, reaching 64 feet per second. (This, as usual, ignores air resistance; if it is a dandelion seed, it might have dropped a foot or two in that time. )

Answer 4

The acceleration of an object in free fall depends on how far from the earth it is. If its near the surface (within about 30 miles) its approximately 9.8 m/ss or 32.2 ft/ss. If its very far from the earth (thousands of miles ) the acceleration will be much smaller.

Answer 5

The rate of acceleration due to Earth's gravity is 32 feet per second, per second. In metric terms, it is 9.8 meters per second per second.

This means that if a lead ball is dropped from a tall tower or a cliff, the object will start to fall, and will speed up as it is falling. At the end of one second, the object will be falling at a speed of 32 feet per second. One second later, the object will be falling at a speed of 64 feet per second. At the end of the third second, it will be falling at a rate of 96 feet per second., and it will be falling at a speed of 32 feet per second faster for each additional second that passes.

This ignores the factor of air resistance. On a lead ball, air resistance is negligible. On a dropped feather, however, the air resistance is enormous, and the feather will fall very slowly; in fact, vertical air currents may cause the feather to rise instead of fall.

In one famous video done by Apollo astronauts on the Moon, an astronaut dropped a feather and a hammer from shoulder height. Because the Moon has no atmosphere, and thus no air resistance, the feather and the hammer fell together at exactly the same speed.

The acceleration due to gravity decreases slightly with increasing altitude. As you move further and further away from Earth, the acceleration factor decreases proportionally to the square of the distance from the center of the Earth.

Answer 6

Let's see . . .

A). The earth's rotation has no effect on the characteristics of gravity.

B). Forces don't accelerate.

C). Does the question refer to the speed of the rotation ? The speed of its effect on gravity ? ? ?

D). Gravity doesn't accelerate.

E). There is no such concept as the speed of acceleration.

While the question may appear ambiguous at first glance, upon closer reading it becomes

totally meaningless.

Answer 7

At the surface of the earth, the acceleration due to gravity (g) is 32 ft/s2 or 9.81 m/s2

Answer 8

Escape velocity for the earth is 6.9 miles/second, or 11.1 km/sec.

Answer 9

The closer towards the center of earth the more pull gravity has. the real answer is unknown because objects are never perfectly round and air plays a major role unless in a vacuum.

Answer 10

The only gravity earthlings can feel is the gravity of the earth itself.
