What is the difference between weight on mercury and weight on earth?
It would go something like this. e = Earth's gravity m = Mercury's gravity e*0.38=m Just put whatever number in Earth's gravity and do the math.
How many orbits around the sun will Mercury make in 1060 days?
Mercury orbits the Sun in about 88 Earth days. So, in 1060 days......You do the math.
How did they discover gravity?
By math.
How did discover gravity?
By math.
How is Saturn compared to earth?
ANSWER:Saturn is 938 million miles from the sun. The earth is 93 million miles from the sun, do the math and (takes his shoes off) and Saturn is 845 million miles from the earth.
Why is the Moon's mass 1 to 80 but its gravity is 1 to 6 when compared to Earth?
Because the moon is also smaller in size, which means that an object on the moon's surface is closer to the center of the moon's mass than an object on Earth's surface is to Earth's center. More precisely, the radius of the moon is 27.3% the radius of Earth, so you are 3.66 times closer to the center of mass. The strength of gravity is directly proportional to an object's mass and inversely proportional to the square of the distance from it. So, if we do the math. (1/80)/(0.273)^2 ≈ (1/80)/0.0745 ≈ 1/6.
Which planet would i be oldest on?
Interesting question. It turns out, gravity slows time. You would therefore age fastest on the planet with the least gravity. As we no longer consider Pluto a planet, that would mean you would be older on Mercury. Mercury, however, is closest to the sun, which also exerts some gravitational pull. Nevertheless, without working the math, I think I would still stick with Mercury. If you and a twin were born at the same time on earth and Mercury, (earth being the heaviest of the four rocky inner worlds), my guess is that by the time you had each lived a century, the twin on Mercury would be a few seconds older. Someone should do the calculations to confirm this--I'm just making wild estimates here. A second way of looking at the question concerns the number of years you would have attained. Mercury orbits the sun 4 times for every earth orbit, so if you were ten earth years of age you would be 41.5 in Mercury years. The further from the sun, the longer it takes a planet to orbit. But aside from the gravitational/relativistic effect, you would still be about the same age.
How do you find how many hours are in a planets day?
Find the rotational time in days compared to earth days. Set up two ratios and do the math.
What is the radius of Arcturus compared to the Earth?
Arcturus has a radius about 26 times that of our Sun.Our Sun has a radius about 109 times that of Earth.So a quick bit of math: 109 x 26 = 2,834 times that of Earth
How would you find the mass of an object by math?
-- Measure the force of attraction between the object and the earth. ("WEIGH" the object.)-- Divide the force by the acceleration of gravity.-- The answer is the mass of the object.
When mercury is the smallest planet why does it have gravity that matches mars which is larger?
Gravity depends on two factors: the mass of an object and the distance from the center of gravity. Mass is a measure of how much matter is in an object. In a uniform gravitational field mass is directly proportional to weight. Mercury has less mass than Mars does but it is also denser , meaning more mass is compacted into a given amount of space, so an object on the surface is closer to the center of mass. In more accurate terms, gravity is directly proportional to the mass of the object exerting it. If you double the mass you double the strength of gravity. By contrast, the strength of gravity is inversely proportional to the square of the distance. If you double your distance you will experience one quarter the gravity. Mars is 1.388 times the diameter and 1.94391 times the radius of Mercury. If you do the math with these numbers you will find that the resulting surface gravity is nearly the same between the two.
What math did newton invent to solve gravity problem?
