Mass, Size, and Density of the Universe This is the missing-mass problem. If this factor of ten holds throughout the Universe, then the total mass in the Universe would be about 6e52 kg. If the missing mass were mostly in the form of hydrogen atoms (which is not at all clear) then the number of atoms would be about 4e79.

Weight The weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton. Density is mass/volume. Index

- Earth weighs about 13,170,000,000,000,000,000,000,000 pounds (or 5,974,000,000,000,000,000,000,000 kilograms). Since Earth is too big to be placed on a scale, scientists use mathematics and the laws of gravity to figure out Earth's weight.

- Scientifically, the weight of a body is the gravitational force acting on the body, and directed towards the center of gravity with magnitude of the force depending on the mass of the body. read more...».

- At the Earth's surface a mass of one kilogramme has a weight of one Newton due to gravity but, if, like the Moon, it is orbiting in space, then it has no weight at all. Incidentally, my physics master at the King's School, Grantham, where Isaac Newton was educated, often reminded us that a force of one Newton is about the weight of an apple.

Age of the Universe The age of the Universe can also be estimated from a cosmological model based on the Hubble constant and the densities of matter and dark energy. This model-based age is currently 13.75 +/- 0.1 Gyr.

What percentage of the universe is thought to be dark energy? For the shape of the universe to be flat, the mass/energy density of the Universe must be equal to a certain critical density. The total amount of matter in the Universe (including baryons and dark matter), as measured by the CMB, accounts for only about 30% of the critical density.

- You are correct, it is a trick question or a question proposed by an individual not familiar with the definition of weight. By definition the weight of the universe is zero. It does have mass, but calculating that value would be an monumental task, and at best it would be not much more than an educated guess. Randolph M · 9 years ago

Gravity Earth and Sun. 3.6 x 1021. NB: kg are actually units of mass (the units of force are N = Newtons, where the force on a 1 kg weight at sea level = 9.8 N). The weight (or force) exerted by a given mass depends on how close it is to the earth’s gravity, so here sea level is assumed.

- Mass and weight example - the moon. In the below example, we've featured an astronaut on earth and on the moon. The Moon's gravity is much less than the Earth's gravity - approximately one sixth. So, a 100 kg astronaut weighs 980N on Earth. On the Moon, the astronaut would weigh only 162.2N. However, the astronaut's mass is 100kg where-ever they are. Weight on Earth: 100kg x 9.8m/s2 = 980N. Weight on Moon: 100kg x 1.622 m/s2 = 162.2N.

What Is the Measure of the Force of Gravity on an Object? The weight of an object is the measure of the force of gravity on that object. The calculation of the weight of an object takes into account both the object's mass and gravitational force.

How many pounds does the earth weigh? The Earth doesn't weigh anything, because the concept of weight only applies to a body which is resisting a gravitational field. The Earth is in free orbit around the Sun. … The MASS of the Earth is approximately 5.97e24 kilograms, or 5,970,000,000,000,000,000,000,000 kg. This is approximately 13e24 pounds, or 1,300,000,000,000,000,000,000,000 pounds.

- W=mg on earth, weight is approximately 10 times the mass of the object. Weight of an object= mass of object x acceleration due to gravity where g on earth ~ 10 ms-2 (=9.81 ms…-2 ) and mass/ kilograms. Answered by The WikiAnswers® Community. Making the world better, one answer at a time.

- Weight is a force caused by gravity. The weight of an object is the gravitational force between the object and the Earth. The more mass the object has the greater its weight will be. Weight is a force, so it's measured in newtons. On the surface of the Earth an object with a mass of 1 kg has a weight of about 10 N.

- It is equal to the magnitude of the force exerted by one kilogram of mass in a 7000980665000000000♠9.80665 m/s2 gravitational field (standard gravity, a conventional value approximating the average magnitude of gravity on Earth).

Weight In science and engineering, the weight of an object is usually taken to be the force on the object due to gravity. Weight is a vector whose magnitude (a scalar quantity), often denoted by an italic letter W, is the product of the mass m of the object and the magnitude of the local gravitational acceleration g; thus: W = mg.

- Being that the moon has a gravitational force of 1.622m/s2, we multiply the object's mass by this quanitity to calculate an object's weight on the moon. So an object or person on the moon would weigh 16.5% its weight on earth. Therefore, a person would be much lighter on the moon. Conversely, a person is 83.5% heavier on earth than on the moon.

- We can calculate the ratio of the gravitational constant to the value at the surface of the Earth as the square of (4000/4007) which equals .9965. If the rocket weighs 100 pounds on the surface of the Earth, it weighs 99.65 pounds at 35000 feet; it has lost .35 pounds, a very small amount compared to 100 pounds. Let's do another problem and compute the weight of the Space Shuttle in low Earth orbit. On the ground, the orbiter weighs about 250,000 pounds.

Dark matter The standard model of cosmology indicates that the total mass–energy of the universe contains 4.9% ordinary matter, 26.8% dark matter and 68.3% dark energy. Thus, dark matter constitutes 84.5% of total mass, while dark energy plus dark matter constitute 95.1% of total mass–energy content.

What is the total weight of the Earth? Earth's mass is 6.580 sextillion tons according to the World Book of Facts 2003 edition. Mass and weight are different. Mass is the amount of matter in an object. Unlike weight, it is not affected by location. Weight is the effect of gravity on mass. Earth is increasing in mass by many thousands of tons daily by the daily accretion of extraterrestrial meteorites and meteor dust.

The Universe Is 13.82 Billion Years Old 1 The Universe is expanding a bit slower than we expected. 2  The Universe is 4.9 percent normal matter, 26.8 percent dark matter, and 68.3 percent dark energy.  The Universe is lopsided. Just a bit, just a hint, but that has profound implications.

The Universe and Solar System The metric unit that is used to describe weight as a measure of the force of gravity is called a Newton. Please select the best answer from the choices provided T F.

Mass versus weight In other words, an object with a mass of 1.0 kilogram will weigh approximately 9.81 newtons on the surface of the Earth (its mass multiplied by the gravitational field strength), since the newton is a unit of force, while the kilogram is a unit of mass.

Mass of a person In the usual units, the mass of something on earth has the same numerical value as its weight on earth. Anything which weighs 150 lbs. on earth will have a mass of 150 lbs. If you ever take a physics course they will try to set up separate units for mass and weight, but it can be confusing.

What is the weight of the Earth? Weight of the Earth The Earth is in orbit around the Sun, or in freefall, so technically its weight is <strong>zero</strong>. <br /> Weight depends on measuring the attraction between two objects, such as a person <br /> and the Earth. It is actually a mutual attraction between their masses.
