Gravity

There is no such "property of water". ANY substance, gas, liquid, object, solid, or mass

travels vertically upward ... "against the force of gravity" ... when a force greater than its

weight acts on it in the upward direction. The statement applies to hot air, molasses, water,

automobiles, airplanes, beach balls in swimming pools, and people with leg muscles.

No, an object's mass remains constant regardless of changes in gravity. Mass is an intrinsic property of an object and is not affected by the gravitational force acting on it. However, an object's weight, which is the force exerted by gravity on the object, will change with variations in gravitational pull.

A gravity plumbing system relies on the natural force of gravity to move wastewater from the fixtures to a sewer or septic system. When wastewater leaves a fixture, it flows through pipes sloped downward towards the main sewer line. The force of gravity pulls the wastewater down the pipes, allowing it to flow freely towards its destination without the need for mechanical assistance.

Zero gravity refers to the phenomenon experienced in space where the effects of gravity are greatly reduced, making objects and individuals appear weightless. This occurs when an object is in free fall, such as in orbit around Earth. Objects can still have weight in zero gravity, but they do not feel the force of gravity acting upon them.

Artifical gravity is created by the outward acceleration (centrifugal force) as an object rotates around an axis of rotation. The magnitude of this outward acceleration is given by the centripetal acceleration, which is the opposing inward acceleration keeping the rotating object in circular orbit around the rotating object. In space, this would be done by rotating a space station until the centripetal acceleration is equal to the acceleration of gravity on Earth. Centripetal acceleration is given by the equation: Centripetal Acceleration = Velocity2/ Radius. As you can see, the magnitude of the centripetal acceleration is largely dependent upon the object's distance (distance) from the axis of rotation. Thus, in a space station that is fairly small (has a small radius), a standing astronaut will feel a different centripetal acceleration in his head than in his feet. Take the example of an astronaut standing up in a circular rotating space station with radius 5m and rotating at a speed of 7 m/s. At the astronauts feet (about 5 meters from the axis of rotation), the astronaut's centripetal acceleration will be given by the following equation. CA = 72/5 --> CA = 9.8 m/s2. This is roughly equal to Earth's gravitation acceleration. Now, lets see the magnitude of centripetal acceleration at the astronauts head. If the astronaut is 6 feet tall (about 1.83 meters), then the radius of rotation at the astronauts head is only 3.17 meters (5 meters - 1.83 meters). The speed of rotation will also be slower because the astronauts head, being closer to the axis of rotation, will have to complete a relatively smaller circle to complete one rotation in the same amount of time as the feet. After calculations, the resulting speed of rotation is 4.289 m/s rather than 7m/s. Thus, the centripetal acceleration at the astronauts head is given by the following equation: CA = 4.2892/3.17 --> CA=5.803 m/s2. Thus, we see a serious inconsistency between the centripetal acceleration at the feet of the astronaut and at the head of the astronaut (9.8 m/s2 at the feet and 5.803 m/s2 at the head). This difference would make the astronaut feel extremely uncomfortable and nauseated, rendering them unable to function at the high level needed for space. Instead, lets look at a large space station design. Take, for example, the Stanford Torus, a design that consists of a large 1.8 km in diameter rotating ring. At this large size, the space station would only need to rotate at one rotation per minute and at a rotating speed of 94.24 m/s in order to simulate Earth's gravitational acceleration. with a radius of 900m, the 1.83 meter difference between a astronaut's feet and head would be negligible and thus an astronaut would feel just as if he or she were on Earth. This is why space stations that intend to simulate gravity should be built large enough to minimize the significance of the difference between the radius of rotation of one's feet and one's head.

Yes, gravity does work in a vacuum. Gravity is a fundamental force of nature that acts over a distance, so it can still exert its pull between objects even in the absence of air or other matter. This is why objects in orbit around Earth, such as satellites, experience the effects of gravity despite being in a vacuum.

It is kinetic energy, pertaining to motion. It is compressed energy, the spring in the stick is in Compression, this energy will be released when the weight on the stick is removed.

I'm sorry. I don't have the answer either. I just had the same question come up. (I am a medical transcriptionist). I am going to research it some more. I was wondering if it wasn't 1.030?

Specific gravity dictated as ten thirty (10.30) should be written down as 1.030.

Joules or eV are units of energy -

In particle phsyics, 1 joule is a very large amount of energy, so sometimes physisits use eV or other adaptated units for the field they work in.

At the end its all the same its a quantity of energy ! 1 rad (or rem) = 0.01 joules per kilogram

1 gray (or sievert) = 1 joule per kilogram

1 rad = 6.24E7 MeV per gram

1 rad = 100 ergs per gram

1 electron volt = 1.6E-12 ergs

1 electron volt = 1.6E-19 joules

1 electron volt = 0.001 keV

1 electron volt = 1E-6 MeV

1 erg = 1E-7 joules

1 erg = 6.24E5 MeV

1 erg = 6.24E11 electron volts

1 MeV = 1.6E-6 ergs

1 joule = 1E7 ergs

No. Specific heat is the amount of heat required to raise 1 kg of material by 1 K at constant pressure, while specific gravity is the ratio of the material's density to a reference density (typically water).

Gravity is caused by the denting of space/time more simply its the force that pulls you down. Larger bodys have a greater gravitational pull. when you have a wing, the air that travels under the wing moves slower then the air traveling over it. when air speed up its pressure decreases. so the higher pressure of the slower air on the bottom pushes up on the lower pressure of the faster moving air. To see an example of this hold to pieces of paper together at the top corners and blow inbetweent he two papers, you would think the will go apart but they will compress bc the air inside is moving faster and being pressed by the higher pressure outside.

9.8 meters (32.2 feet) per second2

Technically when pronouncing acceleration due to gravity the internationally correct way to say is is 9.8 meters per second per second rather than per second squared, but that's just me being picky, sorry

Newton's laws of gravity were groundbreaking when they were formulated and are still widely used today for many practical applications. However, they were later replaced by Einstein's theory of general relativity, which provides a more accurate and comprehensive explanation of gravity on a cosmic scale. So while Newton's laws are true within certain limits and are still useful in many contexts, they are not the complete picture of gravitational physics.

Amethyst is 7.0 on the Mohs hardness scale; it is fairly hard. Amethyst is a member of the quartz family. Most citrine on the market is reported to be heat-treated amethyst.

"Gravitational" refers to the force of attraction between two objects due to their mass. This force is responsible for things falling to the ground and the motion of celestial bodies in the universe. It follows Newton's law of universal gravitation.

Gravity affects deceleration by pulling objects toward the Earth, increasing the force needed to slow down or stop. When an object is decelerating, gravity adds to the resistance force opposing the motion, making it harder to come to a stop. The effect of gravity on deceleration can vary depending on the mass of the object and the force of gravity acting upon it.

As you move further away from a planet or other massive object, the force of gravity weakens. This is because gravitational force is inversely proportional to the square of the distance between two objects. So, the gravitational pull decreases as distance increases.

The center of gravity represents a point where the entire weight of an object can be considered to act. It is the point at which an object would balance perfectly, with all gravitational forces acting through that point. The center of gravity can help determine how stable an object is and how it will behave when subjected to external forces.

Einstein's view of gravity is built upon Newton's but extended to some special situations where Newton's Laws (postulations?) have been shown or suggested not to apply. In particular in the presence of extremely high gravitational forces such as occur close to a black hole and as velocities approach the speed of light.

By measuring an object's inertia. On the ISS they suspend an object between two springs and set it bouncing back and forth. By measuring the frequency of the oscillation, a function of inertia, they can deduce the mass of the object.

Gravity is a natural force that attracts objects with mass towards each other, while electricity is a form of energy resulting from the movement of charged particles. Gravity is always attractive and dependent on mass, while electricity can be attractive or repulsive and dependent on the charge of particles.

You can tell if one object has more mass than another by comparing their weights. The object with a greater weight typically has more mass. You can also compare the density of the objects - denser objects usually have more mass.
