Gravity

There is no such thing as zero gravity. Every mass, no matter how great or small, has a gravitational pull towards you, and you have a gravitational pull towards it. In space, tiny hydrogen atoms fly around, about 1 for every large living room. Even though their gravitational pull on you will be tiny, there will still be gravity, even in deep space or places where there are no planets.

The name is "kerosene", and the density varies from 0.78-0.81 times the density of water (i.e., 0.78-0.81 g/cm3).

It is more accurate to say that more massive planets have stronger gravity. If a planet had the same mass as Earth but a larger radius (i.e. it is less dense) surface gravity would be weaker, as the strength of gravity depends on both an objects mass and the distance from its center.

The specific gravity of borax is approximately 1.73.

The moons gravity pulls on the ocean, creating high and low tides. Depending on where the moon is located in contrast to where you are located, the moons gravity cause a spring tide, which is the largest hight range in high and low tides, and a neap tide, which is the least hight in high and low tides. I hope this helps. :)

G= m.g

To find the value of gravitational force applied on an object (in other but less scientific words- the amount of gravity that pulls an object) you should multiply the mass of the object (m, generally in kg) and the gravitational acceleration (g, generally in ms-2) in that area.

The upward thrust which the surrounding fluid exerts on an object is referred to as the force of buoyancy. This thrust acts through the centroid of the displaced volume, referred to as the centre of buoyancy. The centre of buoyancy is not the same as the centre of gravity which relates to the distribution of weight within the object. If the object is a solid with a uniform density exactly the same as water and the body is immersed in water the force of buoyancy will be exactly equal to the weight and the centre of buoyancy will be the same as the centre of gravity. The object will be in equilibrium with the surrounding fluid.

The mass equivalent to one newton of gravitational force is approximately 0.102 kilograms.

The same

Every time you jump, you experience gravity. It pulls you back down to the ground. Without gravity, you'd float off into the atmosphere -- along with all of the other matter on Earth.

You see gravity at work any time you drop a book, step on a scale or toss a ball up into the air. It's such a constant presence in our lives, we seldom marvel at the mystery of it -- but even with several well-received theories out there attempting to explain why a book falls to the ground (and at the same rate as a pebble or a couch, at that), they're still just theories. The mystery of gravity's pull is pretty much intact.

The gravitational force of attraction between the Earth and any other object acts

continually, with constant strength, no matter whether the object is moving up,

down, sideways, fast, slow, straight, in circles, end over end in a loop de loop,

spinning, twirling, rotating, revolving, any combination of the above, awake, sleeping,

or not moving at all. Makes no difference in the force of gravity.

If you define the "up" direction as "positive", then the acceleration is negative, because it is downward. If you define "down" as positive, then acceleration is negative. You can use any convention; just be sure to be consistent within a particular calculation, to avoid errors.

We do! The strength of the force depends on our masses and the distance

between us.

The gravitational force between two 200-pound people standing 3-feet apart,

is about 0.0000024 ounce of force.

If one of the people had the mass of the Earth and they stood 4,000 miles apart,

then the force would be 200 pounds.

Everywhere. It is so ubiquitous and omnipresent that it is never lost.

no

Most likely not. I say that because A). Gravity is not the limitation that makes it

tough for us to reach light-speed, and B). There's no way to manipulate gravity.

Other than that, it has the sound of a great idea.

It's not actually in the show.

Although realistic, the picture is fake.

It depends what you mean by weight.

When we speak, we erroneously use the word weight for describing mass. The mass (or inertial mass in this case) is the measure of an object's resistance to acceleration and its unit is kilograms. The mass is an intrinsic propriety of an object which never changes. Hence, your mass is always the same, it does not matter where you are.

When we talk about weight we talk about the gravitational force which every object with mass is subject to. The weight takes into account the acceleration derived from the gravitational pull of any given body.

The wight is measured in Newtons and it is calculated by multiplying the mass by the acceleration derived from the gravitational field:

w=mg

The unit for weight is Newtons. The acceleration g on earth is approximately 9.8 m s-2 . This value is related to the mass of the object which creates the gravitational field.

In other words, your weight (expressed in Newtons) depends on the environment.

An object whose mass is 100 Kilograms weights on earth approximately 980 Newtons (w=100 Kg X 9.8 m s-2). If we move the same object to this new planet, on which the gravitational field is 15 times the terrestrial gravitational field its mass will still be 100 Kg but its weight will increase dramatically to 14,700 Newtons (w=100 Kg x 147 m s-2).

As for the the 100 pound object described in the question, we have to convert first pounds into kilograms and then we can calculate its weight on this new planet as well:

100 pounds= approx. 45 Kilograms

On the new planet its mass will still be 45 Kilograms (exactly as on earth).

Its weight on earth is 441 Newtons (w= 45 Kg X 9.8 m s-2).

Its weight on the new planet will be 6,615 Newtons (w= 45 Kg X 147 m s-2).

If we want to use English engineering units and we accept 100 pounds as a measure of mass we can simply say that the 100 pound object would wight 1,500 pounds-force on the new planet.

Being smaller, the Moon's gravity is less than that of Earth.

Enough to attract each kilogram of mass with 9.8 newtons (2.205 pounds) of force, and

to accelerate anything you drop at the rate of 9.8 meters (32.2 feet) per second2.
