Gravity

The anti-gravity suit, also known as a G-suit, was invented during World War II in the 1940s. It was initially developed to help fighter pilots withstand the physical stress of high-speed combat maneuvers.

Scientific research, measuring and experiments are carried out in a controlled environment called a laboratory or lab for short. Chances are that we've all been inside a lab at least once in our lives. Either for education or as a hobby, I think you'll agree that chemistry is truly an interesting branch of science.

With cooking, a chef needs various knives, pans and other tools to cook his "Piece de resistance". Painters need different brushes and paints to create their masterpieces. This is also the same for scientists at laboratories. Laboratory apparatus are different tools and equipment used by scientists to perform their tasks.

The basic types of laboratory apparatus are the glassware, the stands, burners and evaporation equipment. Depending on the experiments and research done in a lab, there could be more equipment. Laboratory apparatus like the beaker, test tubes and flasks fall under glassware lab equipment. These are often used for containing, measuring and observing of liquid chemicals or compounds used in an experiment.

The specific ones that can be used for storing are test tubes with corks or stoppers and glass reagent bottles. Others like the graduated cylinder, graduated beakers and flasks are used to measure liquids. If a liquid needs to be transferred from one vessel to another, the graduated glass pipette, graduated cylinder or a graduated glass dropper can be used depending on the amount of liquid.

Other laboratory apparatus falling under the category of glassware can be used like pans over a lab burner. The evaporating dish for example is a circular piece of glass, sort of like a giant clear contact lens used to evaporate chemicals. A similar looking laboratory apparatus is the Petri dish, often used by biologists to culture cells. The flat-bottomed Erlenmeyer flask was also designed for heating liquids over a burner. The gradual narrowing of the neck is designed to keep more heat from the burner.

Stands and clamps are tools used to hold and stabilize other laboratory apparatus. Examples are the test tube rack, test tube holder and the tripod. A stand and clamp is often used with a flask glass bottom or a test tube. Because the bases of these are curved, the stand and clamp is used to achieve a stable upright position. The tripod is often used with a burner under it.

Bunsen burners are heating devises that function as little stoves in the lab. These are used to provide concentrated heat to evaporate or heat certain liquid solid chemicals. Bunsen burners are fueled by gas often supplied by a gas line installed inside the lab. Modern electronic hot plates can also be used for heating. Some electronic hot plates have curved bases that mold with the shape of a round bottom flask. This not only reduces the risk for spillage, it also rids scientists of gas leak worries.

These are only some of the myriads of laboratory apparatus used in by scientists today. The various fields of science are wide and complex. Knowing the basic laboratory apparatus and their uses is just the tip of the iceberg.

Gravity is a constant force that is determined by the mass of two objects and the distance between them. To decrease the force of gravity, you would need to reduce the mass of one or both objects, or increase the distance between them. However, on a practical level, it is not possible to reduce the force of gravity on Earth.

The acceleration of gravity on Earth is approximately 9.81 m/s^2. This value is a constant and represents the acceleration at which objects fall towards the Earth due to gravity. You can find it by conducting experiments involving free-falling objects and analyzing the data collected.

Gravity is the force that brings an object down towards the center of the Earth. The force of gravity in water is the same as on land, approximately 9.81 meters per second squared (m/s^2). However, in water, objects may experience buoyancy in addition to gravity due to the water's density and upward force.

The planet Uranus is nearly 1.5 billion miles from Earth. It is also around 2 billion miles from the sun.

Mass is a measure of the amount of matter in an object, weight is the force of gravity on an object. Weight is directly proportional to mass and gravity: (Weight = mass \times gravity). On Earth, gravity is relatively constant, so an object's weight is a good indicator of its mass.

it is determine in term of density .

it is the ratio of density of water to the density of milk .

cow milk density is 1.0032

aliens have this right now but we dont, what this does is it disrupts gravity and well there is then no gravity around it. this is how it works, all ufos use the element 15 power source that works like this, a particle is in a circular accelulator it then gets accelulated and therefore gains speed and mass and is then shooted up into element 15 making that change from 15 to16 and it then explodes and a whole bunch of machines take that and turn it into energy and that is how all ufos get there energy. the gravity disruptor works like this, it takes some of that energy and makes it turn a big circular accelulator and in the accelulator is a super ferro fluid whitch is pressurized to 250,000 atmospheres and cooled to 150 kelvin and so then the circular accelulator is turned on and rotates the super ferro fluid and all of that makes the craft lose most of its gavity when withen gravitys pull. now we could build this but when we cool the ferro fluid it freezes and that is why someone has to yet invent a super ferro fluid that does not freeze when cooled to 150 kelvin

EDIT: This answer is half right, the real explanation is a lot simpler , we have the technology the create an anti-gravity field generator (called a Gravitomagnet), this is comprised of a toroid (donut) shaped tube filled with a super ferrofluid, an electromagnetic coil is wrapped around the device and when current is passed through it that causes the ferrofluid to move in a circle arounf the toroid. Now remember a super fluid (such as Helium-4) has no friction once it reaches a certain temperature (roughly 150 degrees Kelvin) so the only way to make it rotate through our toroid is via an electromagnetic field, what's even more interesting is the fact that as long as the super fluid remains at 150 degrees Kelvin it will continue to rotate through the toroid indefinitely because it has no friction due to the fact that it is not a Newtonian fluid. Now we know that the strength of an objects gravitational field is directly proportional to the objects mass, and we also know that mass increases with velocity, so as our super ferrofluid accelerates around the our toroid it's mass increases and therefore it's gravitation field grows stronger.

Gravity is a force that keeps things from floating in mid air. Without it you would have been out of the earth by now!! Gravity is a strength deep under the earth (from the inside). Hope this was useful..

Buoyant force is the force that opposes the weight of an object immersed in a fluid. It is a result of the fluid pressure acting on the object due to gravity. Gravity pulls the denser fluid downward, creating a pressure difference that causes the buoyant force to push the object upward.

Air resistance is a force that opposes the motion of an object through the air, slowing it down. Gravity is a force that pulls objects toward the center of the Earth. When an object is falling, gravity accelerates it downward, while air resistance acts in the opposite direction, reducing the acceleration.

No, gas gravity and specific gravity are not the same. Gas gravity refers to the ratio of the density of a gas to the density of air, while specific gravity is the ratio of the density of a substance to the density of a reference substance, typically water.

Operation Torch was an operation by the Allies during WW2 where British and American forces invaded French North Africa. The center of gravity for the entire operation was arguably the successful Air Force landings in Algiers.

The force due to gravity is called your weight. This force causes an acceleration.

The acceleration due to gravity on the earth is 9.81 m/s/s.

W = m g

g = acceleration due to gravity = 9.81 m/s/s

The photons are affected because the gravitational field affects space-time. Therefore, the photons are responding to the shape of space-time rather than the gravity itself.

The photons in question i suppose are coming from stars and that means they are traveling through space and space is a clear medium. When light travels through a medium it's frequency is lowered and its direction changes. If you were referring to the 1919 eclipse, the stars behind the sun that became visible was due to the suns coronal medium that their light passed through. It was an optical illusion. gravity guru.

The force that makes things fall downwards is gravity. Gravity is the attraction between two objects with mass, causing objects to be drawn towards each other. On Earth, the gravitational force pulls objects towards the center of the planet, which is why things fall downward when dropped.

That depends on the mass, because Force=Mass x Acceleration.

So the force due to gravity (in Newtons) is the mass of the object (kg) x 9.8m/s2 or (N/Kg)

No

It is impossable to create energy or matter from nothing.

The only way to create new energy is by converting mass (matter) to energy, an example of this is nuclear fission. In nuclear fission an atom (normally putonium) is split in half creating an least 2 new elements, but not all of the mass form the original element still remains mass. A small amount of this mass is converted into energy.

No, gravity only pulls objects towards each other in a forward direction. There is no evidence to suggest that gravity can travel backwards.

To convert 20000 kg of Jet A1 fuel with a specific gravity of 0.86 to liters, you would use the formula: Volume (liters) = Mass (kg) / Specific Gravity. Therefore, Volume = 20000 kg / 0.86 = approximately 23255 liters.

Theoretically, if there is no (negligible) gravity in a specific area, there will be no atmosphere (outer space is a good example).

So, theoretically......there would be no air resistance.

Classical gravity between two objects is proportional to their total mass and the inverse of the distance between them squared, that is Gravitational force = g x (m1 + m2) / d2 where g is a constant, m1 and m2 are their masses and d is the distance between their centres of mass. In the real universe things are MUCH more complicated. For Einstein's equation and others see the related link below.
