For the most part, yes; the weight of an object is equal at any point on the Earth as measured by any standard scale. However, using a gravimeter it is possible to detect minute differences in gravitational force. These differences are due to differences in topography or rock density at the site of measurement. For example, a gravimeter will yield a slightly lower gravity measure if read above a granite slab (low density) than it would over a basalt slab (high density), providing that both slabs are at equal altitude and are thick enough to be detected by the gravimeter (often on the order of 10s-100s of meters thick). Measuring gravity is how many features below the ice on Antarctica have been mapped, and is often how oil fields are discovered.

When is acceleration constant?
We have constant acceleration all the time. Its called gravity. Gravitational acceleration is 9.8... m/s^2
Is work defined as force times parallel distance?
No. Work is transferred energy. When you do work, you are transferring energy. If the force is constant over time: Work = F*d*cos(theta) where F = force d = distance object travels over the time the force is applied theta = angle between force and the displacement of the object The only component of the force that can do work is the component of the force that is parallel to the displacement.
What does the word constant mean?
Constant means something will go or play over and over again. Example: He is very constant at basketball!
Can you fly an earth small circle?
YES. A small circle is simply a circle around the earth that does not fly over the direct opposite place on earth that a plane took off from. A great circle goes full circumference of earth, where a small circle does not. Being a circle they both fly in a constant direction.
What is flat surface?
A flat surface generally refers to a horizontal surface and is referred to as the plane.
Why does the gravitational force between the Earth and moon predominate over electrical forces?
Between the Earth and the Moon, for example, there is no net electrical force. So the weaker gravitational force, which is only attracts, remains as the predominant force between these bodies.
Over millions of years the moon is moving further away from the earth what will happen to the gravitational attraction between the moon and the earth as the moon gets further away?
As the moon gets further and further away, the gravitational force between the Earth and the Moon decreases. Because the Moon is not being attracted but being pushed away from the Earth. If the gravitational force would have increased, the moon would come closer and closer to the Earth.
In which direction does earth's gravitation force act?
It is a linear force towards two centers of gravity: you and the earth. While the earth exerts a strong gravitational pull on you, you exert a gravitational force upon the earth, although it a much lesser force since you have far less mass than the earth. To go even further, the magnitude of the sum of forces would be 9.81m/s2 plus your body's gravitational acceleration, whatever that number may be. So let's say that the gravitational force that you exert is 0.001 m/s2, then the total magnitude would be 9.82m/s2. This was answered with credible sourceOld Answer: It`s NOT your face ser.
Why is g called the universal constant?
It is the measure of the gravitational force experienced between any two bodies, anywhere in the universe. So, the same number is used to calculate the gravitational attraction between bodies anywhere in the universe. There are, however, some questions as to whether is is (or was) a constant over time.
Which force is responsible when a ripe fruit falls from a tree?
Of course, the gravitational pull of the earth is the prime factor here. The apple is being pulled to the centre of the earth, but in most cases is blocked by something .Example, the ground. Gravity is pulling everything toward it, but depending on how heavy it is determines how much force that gravity has over the object. For example: Gravity has more control over a car than a helium balloon, because the heavier the object, the more gravitational pull it conducts.
What is the force from gravity?
If your question rephrased is 'What force does gravity give?' then the answer would be a Gravitational Force. In depth, a Gravitational force is a pulling force which, when opposing other forces, is usually over 55% dominant.
What is the gravitational force called gravity?
It is the force one object exerts on another just because they have mass. Every object attracts every other object because they have mass and the strength of the force is proportional to the masses. In everyday life the gravitational force on you from say a nearby building is to small to be felt. The only gravitational force on you that can be felt is the one caused by the earth underneath you (because the earth's mass is so large) and we call that particular gravitational force your weight. In fact, the earth's gravitational force on any object near its surface is called its weight.
12 Would it ever be possible for the moon to exert more gravitational pull on ship than the earth would?
No. This would be impossible. Isaac Newton showed in his Law of Gravitation that gravity depends on three things: 1. The Gravitation Constant - a tiny number (symbol G) that is universal across the univers that is a measurement of the strength of the force of gravity compared with other forces like magnetism. It is approximately 0.00000000006 2. The masses of the objects between which the force acts - the larger the mass the larger thr force 3. The distance between the objects - the smaller the distance the larger the force. So in the case of the ship, (a) the gravitation constant would be the same for the earth, ship and moon so this constant would be irrelevant in this case. (b) The earth is much more massive that the moon and so would exert a greater force on the ship than the moon ever could. So the earth would exert more gravitational pull than the earth. (c) The earth is nearer to the ship (just the depth of the sea away!) than the moon (over 240,000 miles away!) and so the earth would exert a larger gravitational pull. So the earth wins on both counts!
How does the strength of electrical force compare to the gravitational force?
Electrostatic forces are similar to gravitational forces in that they both conform to the distance squared law and are proportional to the properties of the two actors in the interaction (in terms of electrical forces, the charges of the two point charges; and in gravitational, the masses of the two bodies). However, though their interactions looks similar the greatest difference is their strengths. The constant of scale for electrostatic forces (Coulomb's constant) is about 9 x 109 in magnitude, whereas the constant of scale for gravitational force (gravitational constant) is about 6.67 x 10-11 in magnitude. Therefore, the electrostatic force scales much faster than gravitational force. Therefore, it is common to see large objects such as the earth exert a tiny force with respect its size, while a small charged Styrofoam ball can push another with relative ease.
What is the formula for force constant?
Fc = mv^2/r Or Force constant = Mass X Velocity Squared Over Radius.
Most waves are caused by what blowing over the surface of the water?
The gravitational pull of the moon combined with the gravitational pull of the earth causes the water to be pulled back and forth.
Why won't a helicopter that hovers for 12hrs end up on the other side of the earth when it lands 12hrs later?
The helicopter that is hovering over a place on the earth is n bound to the earth by the gravitational force of the earth. This gravitational attractive force on the helicopter is directed towards the center of the earth. As the earth rotates around itself the helicopter is pulled along with it. So the point directly below the earth's surface does not get displaced. Thus the helicopter cannot move away from the spot. For the helicopter to get itself free from the gravitational pull of the earth it has to be lifted to a height of millions of kilometers, where it cannot hover because a helicopter requires the presence of air to hover.
