Mars has less mass because it is a smaller planet that is made up of roughly similar matter.

The mass is the same everywhere. It is the weight that could be different according the difference in gravity among the planets.

Does mars have stronger grtavity than earth or weaker?

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.


Why would you weigh less on Mars than on Earth?

On Mars, you weigh 37.7% as much as you would on Earth. If you weigh 100 pounds on Earth, you weigh only 37.7 pounds on Mars. If you weigh 150 pounds on Earth, you weigh only 56.6 pounds. The equation is .37 x Earth weight = Martian weight.


Why would you weigh the least on mars?

Mars is a smaller planet than Earth. Your weight is the product of two masses yours and the planets Your mass stays the same wherever you are, if you stand on a smaller planet, you weigh less.


Why is the weight of a buggy less on Mars than on Earth?

The gravity on Mars is less than on Earth, so although the mass of the buggy is the same on Earth and Mars, its weight is different because weight is equal to mass multiplied by the gravitational force. The gravity of Mars is 38 percent less than that of the Earth's. So, something that weighs 100 pound on Earth will weigh 38 pounds on Mars.


Which planets are lighter than earth?

The planets that have less mass than Earth are Mercury, Mars and Venus. The planets that have a lower average density than Earth are all of them; Earth is the most dense planet in our solar system.

Does the moon or Mars have less gravity?

The moon has less mass than does Mars and therefore has less gravity at its surface.

Why do objects weigh less on mars than they do on earth?

Objects weigh less on Mars than on Earth because Mars has less mass than Earth, resulting in weaker gravitational pull on objects. This weaker gravitational pull means that objects weigh less on Mars compared to Earth.


Does mars weigh more than earth?

No, because it is only slightly larger than Earth's core, but is off an almost equal density.


Does earth have stronger or weaker gravity than mars?

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.

Why would you way less on mars than on earth?

You would weigh less on Mars than on Earth because Mars has less mass than Earth, so it exerts weaker gravitational force. This means that the pull of gravity on your body would be lower on Mars, leading to a decrease in your weight.


Does the earth have more mass than mars?

Yes. Earth is about 6.5 times larger than Mars and has more mass.
