CONTENTS the mass of the Earth. Solve for the mass of the Earth: m1 = aR 2/G = _____ kg Questions 1. Why is it a good idea to take many measurements and average the results? 2. Compare your value for the mass of the Earth to the true value of 6 x 1024 kg. That is, calculate the percentage difference: 3. How does your value for the acceleration compare to the actual value of 9.8 m/s2? With this answer in mind, how does your measurement for the acceleration of an object affect your derived value for the mass of the Earth? 4.

Earth The Hill sphere, or gravitational sphere of influence, of Earth is about 1.5 Gm or 1,500,000 km in radius. This is the maximum distance at which the Earth's gravitational influence is stronger than the more distant Sun and planets.he mass of the oceans is approximately 1.35 × 10 metric tons, or about 1/4400 of Earth's total mass. The oceans cover an area of 7014361800000000000♠3.618×108 km2 with a mean depth of 7003368200000000000♠3682 m, resulting in an estimated volume of 7018133200000000000♠1.332×109 km3.

Thread: How much of Earth's mass is water by weight percentage? Well google says: mass of Oceans = 1.384 × 10^21 kg (Modified from Clark, W. C. (ed.). 1982. provided those numbers are accurate and my sans coffee morning number juggling is correct, it looks like the oceans have somewhere around 2 one hundredths of a single percent of the mass of the Earth.

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.

Ocean Physical properties. The total mass of the hydrosphere is about 1.4 quintillion metric tons (7018140000000000000♠1.4×1018 long tons or 7018150000000000000♠1.5×1018 short tons), which is about 0.023% of Earth's total mass. Less than 3% is freshwater; the rest is saltwater, almost all of which is in the ocean.

Density of the Earth I also calculated numbers for the density of the Earth. I knew the mass of the Earth in grams is 5.979 × 10 27. Also, the radius in centimeters is 6.3713 × 10 8. I plugged this information into the 4/3πr 3 formula in order to find the volume. I got the answer 1.084227366 × 10 27 cm 3.

Gravity of Earth The gravity of Earth, denoted g, refers to the acceleration that the Earth imparts to objects on or near its surface. In SI units this acceleration is measured in meters per second per second (in symbols, m/s2 or m·s-2) or equivalently in newtons per kilogram (N/kg or N·kg-1).

Gravity of Earth The gravity of Earth, which is denoted by g, refers to the acceleration that the Earth imparts to objects on or near its surface due to gravity. In SI units this acceleration is measured in metres per second squared (in symbols, m / s 2 or m·s −2) or equivalently in newtons per kilogram (N/kg or N·kg −1).

- The mass of Earth is 5.97 x 10 24 kg. Here that is written out: 5,970,000,000,000,000,000,000,000 kg. Yeah, that’s a really big number. And yet, it’s only 0.3% the mass of Jupiter (and Jupiter is mostly lightweight hydrogen).We have written many articles about Earth for Universe Today.Here’s an article about how fast Earth rotates, and here’s an article about Earth’s magnetic field.he mass of Earth is 5.97 x 10 24 kg.

Mass of a person mathman said: ↑. 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.

Hydrosphere 29.9% is in the form of fresh groundwater. Only 0.26% of the fresh water on Earth is in easily accessible lakes, reservoirs and river systems. The total mass of the Earth's hydrosphere is about 1.4 × 1018 tonnes, which is about 0.023% of Earth's total mass. About 20 × 1012 tonnes of this is in Earth's atmosphere (for practical purposes, 1 cubic metre of water weighs one tonne).

- gravity is the force by which the earth or any heavenly body attracts a mass towards its centre. the gravitational force depends on the mass of the heavenly body and the mass …of the other body on which it acts. the gravitational force of the earth is 9.8 newtons. on a mass of 7 kgs on earth,the force would be 9.8 by 7 that is 68.6 newtons.

How do scientists measure or calculate the weight of a planet? Because we know the radius of the Earth, we can use the Law of Universal Gravitation to calculate the mass of the Earth in terms of the gravitational force on an object (its weight) at the Earth's surface, using the radius of the Earth as the distance.

Geodesy and the Size and Shape of the Planet Earth Earth's Size. As the largest of the terrestrial planets, Earth has an estimated mass of 5.9736 × 10 24 kg. Its volume is also the largest of these planets at 108.321 × 10 10 km 3. In addition, Earth is the densest of the terrestrial planets as it is made up of a crust, mantle and core.The Earth's crust is the thinnest of these layers while the mantle comprises 84% of Earth's volume and extends 1,800 miles (2,900 km) below the surface.n addition, Earth is the densest of the terrestrial planets as it is made up of a crust, mantle and core.
