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.
What else can I help you with?
When is acceleration constant?
constant acceleration is when you gain the same speed over the same time
Why has earths diameter remained fairly constant?
Earth's diameter has remained fairly constant due to a balance between geological processes and gravitational forces. The planet's solid crust and mantle undergo continuous processes like plate tectonics, which can reshape its surface but do not significantly alter its overall size. Additionally, the gravitational forces acting on Earth help maintain its shape, preventing significant changes in diameter over time. While factors like erosion and sediment deposition can cause local variations, they do not affect the planet's overall dimensions.
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!
Which forces have infinite range?
The gravitational force and the electromagnetic force have infinite range. Gravitational force acts between any two masses, regardless of the distance separating them, while electromagnetic force operates between charged particles over any distance as well. Both forces diminish with distance but never completely vanish, allowing them to influence objects even at vast separations. In contrast, the strong and weak nuclear forces have limited ranges, operating only at subatomic scales.
How does the moons gravitational force affect the crust of the earth?
The gravitational force of the moon causes tidal bulges in the Earth's crust, leading to the rise and fall of ocean tides. This gravitational interaction between the moon and the Earth also contributes to the phenomenon of Earth's rotation slowing down over time.
What will eventually happen to the gravitational force between the earth and the moon?
The gravitational force between the Earth and the Moon will continue to exist and affect their orbits. Over time, tidal forces will cause the Moon to move further away from the Earth, which will result in a weaker gravitational force between them.
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.
Does the gravitational constant change over time or is it a constant value?
The gravitational constant, denoted as G, is considered to be a constant value in physics. It is a fundamental constant that is believed to remain the same over time and across the universe.
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.
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!
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.
What is the equation for tidal force and how does it affect the Earth and its oceans?
The equation for tidal force is F G (m1 m2) / r2, where F is the force, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them. Tidal force causes the Earth's oceans to bulge towards the Moon and Sun, creating high and low tides. This force also creates friction, leading to the slowing down of the Earth's rotation over time.
What affect the magnitude of force?
Gravitational Force = Gravitational Constant x mass of the first object x mass of the second object / distance squared. So what affects the magnitude is the masses of the objects and the distance between them. Gravitational Constant = 6.672 x 10^-11 N x m^2/kg^2 Both masses, and the distance between them.
Is the speed at which the earth rotates constant?
Yes, the speed at which the Earth rotates on its axis is relatively constant, at about 1670 km/h at the equator. However, factors such as gravitational interactions with other celestial bodies can cause slight variations in its rotational speed over long periods of time.
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.
What forces shape the moon's surface?
meteorites are one force when they impact. However, the key force acting on the moon is the force of gravity. The gravitational force is = G (m1 m2)/r2. Where G is the universal gravitational constant, m1 is the mass of one object, earth let's say, and m2 is the mass another object, say the earth. "r" is the distance between the two objects. The earth mass is larger, which is why it holds the moon in an orbit around itself. But the moon still effects the earth with tidal forces on the oceans and atmosphere.
