There is no particular reason: some planets have more mass than others.
Yes. Earth is about 6.5 times larger than Mars and has more mass.
Really small. 3.68x10^37% in scientific notation.
No. Mars is a little more than a tenth the mass of Earth.
The mass of mars is about 0.107 Earth masses.
Mars would have to find more mass if it wanted to equal the Earth's. It has only 11% of Earth's mass.
No. Mars has about one tenth of Earth's mass. Venus, howevr, does have a similar mass to Earth.
Earth is more massive than Mars and therefore has greater gravity.
No, Mars has a greater mass than Venus. Mars has a mass of about 0.107 times that of Earth, while Venus has a mass of about 0.815 times that of Earth.
Because Mars is a lot less massive than the Earth. The surface gravity depends on the mass of the planet you are standing on, and since Mars is lighter the surface gravity there will be less than here on Earth.The gravitational force between two objects depends on their mass and the distance between their centers of mass. Mars has a smaller radius than the Earth (which would tend to increase the gravitational force), but it has a much smaller mass than the Earth (which tends to decrease the gravitational force). Combining the two factors, it works out that the surface gravity of Mars is about one-third that on Earth.
You need to:1) Divide the weight by Earth's gravity, to get the mass. 2) Remember that the mass will be the same on Mars. 3) Multiply the mass by the gravity of Mars, to get the weight on Mars.
Mars is 0.107 times the mass of earth. The reciprocal of that is the number of planets the mass of Mars it would take to equal a planet the mass of earth, or a little over 9 and 1/3.
The gravitational force exerted at the surface (and above the surface) of Mars is weaker than that here on Earth. The reason: Mars has less mass than earth.
