The specific gravity for water is 1. However, when the temperature of water increases, the gravity gradually lowers. At 0°C (32°F), gravity is 1. At 100°C (212°F), the specific gravity of water is 0.958. At 300°C (approx. 580°F), it is 0.7.
There is indeed a relationship between gravity and atmospheric pressure. Gravity attracts matter with mass, in this case gas. The atmosphere being a layer of gas, the stronger the gravity, the higher it's pressure. I if you seal gas in a tank, and increase its mass (by adding more gas)...
The ease with which an object can be balanced depends greatly on the location of its center of gravity. In this video segment adapted from ZOOM, two cast members experiment with various designs in an effort to balance a pencil on its tip. Their solution lowers the pencil's center of...
I think you mean a pen. A pen isn't able to be used in zero gravity because the ink needs to move to the ballpoint where the ink exits. Thus, pens need the ink to flow to the tip of the pen so it comes out the ball roller, which without gravity won't work as well.
The attraction of the earth on the thrown object is called 'Gravitational attraction' or 'gravity' , and the change in velocity of the object , as the result of this attraction , is known as 'Acceleration due to gravity'
Because the slopes are sliding it is easy for gravity for pulling...
yes. gravity is the force of one object attracting another
Gravitational Force increases with increase in mass but the acceleration due to gravity remains the same irrespective of the mass i.e. 9.8m/s2
There is Inertia with newtons law that an object in motion stays in motion. There is gravity holding it down.If the object is at rest, there is no force acting upon it. Force = mass x acceleration (F=ma). Inertia is not a Force, and the net gravitional Force is zero because the downward acceleration...
it does, but they flap their wings to lift them up
No. Space is literally nothing. No oxygen, no air, no dust, nothing. objects in space, yes, the earths gravity does affect it. otherwise the moon would just fly away.
The attraction between two objects is: G x m1 x m2 / distance squared where m1 and m2 are the two masses involved, and G is the gravitational constant - approximately 6.674 x 10 to the power -11, in SI units.
By contributing to innovations in the Quantum Theory
Yes. But different value of gravity. It is nearly close to 0.
"Gravity is a distortion in the Space-Time Continuum" -Albert Einstein...
Gravity is a force measured in Newton's (N)
It would effect the object by it's density (The amount of mass within a confined space). The density times the object's gravity would be how fast that object would accelerate.
OK, if the mass is small and close to the surface of the Earth, then the force of gravity is a constant downward. Two more similar sized objects show a (1/distance) squared relationship that is proportional to each mass.
Yes. Gravity is a property of mass.
Rather than Gravity , it is Electromagnetic forces which are holding all atoms together and giving the shape of material bodies
Gravity is a field or a force, and, hence, has little to do with speed.
you can see the presence of gravity all around as that is what holds us to the earth and gives us weight.
Well, back when the first human was around, I don't think there were any countries. However, Gnarl Tukee of the Gnishmash clan I believe discovered it a few seconds before he fell to his death.
yes it effects and gravitational pull is inversely proportional to the square of distance between two objects: G = gm1m2 /r2
No, unless they are near a body with enough mass to have gravitational pull. For example, standing on the moon they would feel gravity (although it's a lot less than Earth's gravity ) but floating in space technically there is still gravity but it is such a small force that an astronaut...
it was Issac Newton. He was sitting under a tree and an apple hit his head and thats when he knew that all objects fell downwards
Gravity affects the bounce of a basketball because if there is gravity, the basketball will come back down after it bounces. But if there is no gravity, the basketball will bounce and travel indefinitely upwards and never come back down until a gravitational force pulls the basketball towards it.
It is the universal force of attraction that acts between all bodies that have mass. Though it is the weakest of the four known forces, it shapes the structure and evolution of stars, galaxies, and the entire universe. The laws of gravity describe the trajectories of bodies in the solar system and...
Throughout your everyday life, any time that you move, your speed that you move at is lessened by inertia. This also holds true to gravity; if you were to trip, without inertia you would accelerate into the ground quickly and likely hurt yourself. The property of inertia is invariably...
Because the force of gravity is diluted by distance. We are far enough from the Sun that it can't just pull you off the Earth.
The best title for your project is one that encapsulates what your project is about. It should be short, but still memorable. A good title sets the tone for an entire project, so be sure to spend some good time on coming up with a title.
Due to evolution, most species would become smaller, so they could move properly if the gravitation rised, and got bigger, if the gravitation falled.
no, but the electromagnetic field of the earth does.
This does seem odd. Mars, with a mass that is about twice the mass of Mercury, has about the same surface gravity. Mars' mass is about .107 the mass of earth, and the mass of Mercury is about .055 the mass of earth. The surface gravity on Mars is about .38 times the surface gravity of earth, and the...
Though weight is effected by gravity, mass is not affected by gravity. Actually mass is affected by gravity. Although the amount of mass is not affected by gravity, mass itself is.
Weight is the force of gravity between the earth and any object on it, and the object's weight is completely determined by the laws of gravity.
Level 6: Drop a big stone on the end of the level and flip the ball up.
From memory the gravity is around 3.7ms-2
Gravity exists because the Earth has mass. If the Earth was massless, gravity would not exist and people would freely float away into space. Acceleration due to gravity is always -9.81 m/s^2 on Earth.
No one has yet figured out how to counter-act gravity.
The force exerted by the earth's gravity on an object on its surface is approx (9.8) x mass of the object) newtons. Acceleration due to gravity is 9.8 m/s2 and force = mass times acceleration (Newton's Law). The reason I say approximately is that the earth is not perfectly spherical, meaning the...
It's an older term; nowadays the phrase "Center of mass" seems to be preferred. It's, basically, the mass-weighted center of a ... well, a thing. The center of a sphere of uniform density is easy to calculate; it's the geometric center of the sphere. For other shapes or for objects where the...
Gravity has no effect on the mass of an object. However, an object's weight is the measurement of gravitational force on the object. The gravitational force on the moon for example is ~ 1/6 of that on Earth.A 300 kg object would weigh 3000N (Newtons) on the Earth but only weigh 500 N on the Moon but...
If the solar system did not have gravity then it would have never formed.
Every speck of mass in the Universe 'has gravity'. That includes every planet, comet, asteroid, meteoroid, moon, artificial satellite, space ship, star, grain of dust, person, car, dog, dish, shoe, goldfish, doorknob, rock, computer, soda can, cellphone, and the lint in every pocket. Every one of...
acceleration has everything to do with gravity
It has a very tedious one just although enough to rise the sea levels by high tide.
No, you would not be able to walk on uranus. The person above is abosultely wrong. Everything with mass has a gravitational force. Uranus is much more massive than Earth, so obviously there is more gravity. I dont not know if it has 'too much'
The force of gravity is still there - and far out into space, but in the case of an orbiting body, it is exactly balanced out by the centrifugal force - or is it the centripetal. You research that last bit.
Birds is use they wing to keep them up. They flap and up in air.By moving their wings in a flapping motion, along with angling their bodies and internally measuring their speed, they are able to maintain a constant elevation. Some birds travel in V forms to ease the burden on the bird behind them,...
Not at all. The force of gravity between two objects depends only on their masses and the distance between their centers. Their volumes have no effect.Another answer:As for as one object goes:Density of an object increases the escape velocity (or escape speed) which increases the gravitational...
The diver and the Earth actually pull on each other with the same force. But with Force = mass x acceleration, rearrange that to: Acceleration = Force / mass. With such a large mass, the Earth is accelerated by a miniscule amount. Compared to the acceleration of the diver, it is not noticed.
You have to use energy to raise a mass against the gravitational force, the object then has potential energy. If it is then let fall, this potential is released.
The mutual gravitational force between two objects is inversely proportional to the square of the distance between them. If the distance increased by a factor of 10, the force would decrease, and would become 1 / 10 2 = 0.01 times its original value. The original 500 newtons would...
If these two points do not coincide the two forces will also produce a couple that will rotate the body of the plane. If they do coincide the plane will rise, fall or stay at the same height without rotating about some axis. So yaw, pitch or roll is effected by offsetting the centre of pressure in...
inertia pronounced in-er-sha
Gravity is needed for buoyancy as if there was no gravity then there would be no need for buoyancy, the need for buoyancy is to counteract the pull of gravity so you can stay at the surface of a liquid such as water. If there was no gravity then there would be no need to counteract it. I hope this...
The force of Earth's gravity on the 4-kg book is stronger than theforce of Earth's gravity on the 2-kg book.
== Answer == where did you hear that from?
The force of attraction between all masses in the universe.
Zero gravity would be fun in small doses, but after a short time in zero G, there can be many problems: --Bone & Muscle Loss (you don't have to work as hard to move, or stand), you will return to Earth much weaker --Swelling of the face (body is used to fighting gravity to...
Gravity draggs the roots under whilst the roots try their best to pull upwards. This increases the plants strength and therefore it will grow quicker.
The surface gravity on Pluto is a little more than 6% of the gravity on Earth, which is less than half the gravity on the moon.
Gravitational Potential Energy is equal to Potential Energy therefore the formula for GPE (Gravitational Potential Energy) is PE=mass x gravity x height therefore the formula is PE=mgh
Yes, but it is only about 1/6th as strong as Earth's gravity.
There is a whole book to be written speculating about how life would be if Earth's gravity was weaker or stronger. Let's assume weaker gravity for this discussion - whatever applies to weaker gravity probably applies in reverse for stronger gravity. The most obvious effect of weaker gravity on...

The quantum theory of gravity is that they are made up of particles called gravitons. This theory is in the early stages, though.
Everything with mass is a source of gravitational forces, and is influenced by them.
well if you're on earth then yes. If u are an alien from somewhere without gravity then no.
32 feet per second squared. 9.8 meters per second squared.
It will accelerate upward. When it reaches the surface and part of the object sticks out of the fluid, then the buoyant force decreases. When enough of it sticks out so that the buoyant force exactly equals the force of gravity (the object's weight), then it stops rising...
It could cause your muscles to weaken or deteriorate depending on how long a person was exposed to it. If a person is exposed to it they need to make sure and do plenty of exercises to keep their muscles in shape.
I don't know, but if it did, I have some theories why it might help. Hanging upside down might... - Temporarily increase the gap in the knee, allowing better circulation and regeneration of cushioning cartilage.- Relax tense leg muscles that are causing the patella to mis-track- Promote some change...
You can oppose gravity by some other force. For example, you can lift something up with your hand.
Because roller coasters are required to have harnesses, belts, or other such things to keep your strapped in when they go.
There are many different types of forces in the world based on definition. Many people consider gravity a force for example.
No, heart transfer has to do with conduction, convection, and radiation. In all of these actions energy is moving from higher concentrations to lower concentrations. Gravity is just a naturally occurring force in nature... It's origins are to be answered in another question.
On Earth, gravity pulls matter down at 9.8 meters per second when the object is falling.
No gravity is the weakest force. The proper order is strong force, Electromagnetic, weak force, then gravity
gravity decrease according to inverse square square law
