Well, honey, gravity ain't picky - it's the same everywhere! Both Mars and Mercury have gravity, but Mars is a bit heavier with about 0.38 times the gravity of Earth, while Mercury is even lighter with about 0.38 times the gravity of Earth. So, technically, they're both playing in the same gravity sandbox, just with different sized buckets.
What else can I help you with?
Is gravity on mars the same as on earth?
No. Gravity on Mars is about 38% of what it is on Earth.
What planet has the force of gravity here that has less than half of the pull exerted by gravity on earth?
I'm not sure if it's half or not, probably less, but the only possibility would be Mercury. True. Mercury is the only one. Gravity on Mercury's surface is 37% of what it is on Earth. Except for Mars, where it's 38% of its value on Earth. Mercury and Mars are the only ones. Except for Pluto, where it's 4% of its value on Earth.
What has more gravity moon or mars?
Mars has 38% approximative gravity to that of Earth, meaning Earth has almost three times as much. While the moon has 16.7% that of the Earth. Meaning Mars has a stronger gravitational pull then that of the moon.
What two planets are almost the same size?
Mercury and Mars are the two planets that are almost the same size in our solar system. Both planets have a similar diameter, with Mercury being just slightly smaller than Mars.
What is gravity on Mars compared to earth?
The gravity on the surface of Mars is approximately one third of that on the surface of Earth. Comment: I always say "about 38%".
Is gravity the least on Mars or Mercury?
Mars
Would you be squished by extreme gravity on mars?
Not by the Martian gravity at any rate. The gravity on the surface of Mars is weaker than on Mercury.
Why does Mercury and Mars have less gravity than Earth?
Why does Mercury and Mars have less gravity than Earth because they both have less mass than does the Earth.
Is mars the smallest planet in out solar system?
No. Mercury is the smallest planet in the solar system, with the lowest mass. Mars has a diameter about 1.4 times that of the denser Mercury, giving them roughly the same surface gravity.
Is gravity on mars the same as on earth?
No. Gravity on Mars is about 38% of what it is on Earth.
Which planets surface gravity is 38 percent that of earths?
Both mercury and mars have a gravity which is around 38% of earths. Mercury's gravity is 37.8% of earths, Mars' gravity is 37.7% of earths.
How does a planet's size affect its gravity?
The distance between a planet and an object affects the gravitational force between them. That means the size of a planet affects the value of the "surface gravity" for that planet. The greater thedistance from the surface to the center of the planet, the smaller the gravity at the surface (for the same planet mass). An example is the fact that Mars and Mercury have almost exactly the same surface gravity. Mars has more mass than Mercury, but this is balancedby the fact that Mercury hasthe smaller radius.
Why is gravity bout the same on mars and mercury?
I'm going to give you more information than you're expecting, because theanswer to your question beautifully illustrates some subtle things about gravity.You asked: Why is gravity about the same on Mars and Mercury ?Is it really about the same ? Yes it is.3.722 m/s2 on Mars, 3.697 m/s2 on Mercury ... less than 1% difference.Why ?What is it that determines the strength of gravity on a planet ?Two things: > The mass of the planet, and > its radius ... the distanceof the surface from the center.How do these numbers compare for Mars and Mercury ?Mass:Mars has 95% more than Mercury . . . not nearly the same !Radius:Mars' is 39% bigger than Mercury's . . . not nearly the same !So how can they wind up with almost exactly the same gravity ?Answer:The gravity on the surface of the planet depends on both of these physicalcharacteristics. It's proportional to the mass of the planet AND inverselyproportional to the square of the planet's radius. So let's look at thecombination of mass and 1/radius-squared for these two planets:(Mass)/(radius)2 :Mars: (0.107 x Earth's)/(0.532 x Earth's)2 = 0.3781Mercury: (0.055 x Earth's)/(0.383 x Earth's)2 = 0.3749That number for Mars is only 0.85% more than Mercury's number.THAT's how they wind up with almost the same surface gravity.
Is the gravity on mars the same as on earth?
No. Surface gravity on Mars is 37.6% (about 3/8) what it is on Earth.
Why do Mercury and Mars have no atmospheres?
Their gravity is too weak to hold on to atmospheric gases.
Does Gravity act on the mars rover?
Yes, gravity does act on the Mars Rovers. On Mars, the gravity on the surface is 39% as strong as it is on Earth. This is also about the same amount on Mercury. A man weighing 200 pounds on Earth (or 440 kg) would weigh 78 pounds on Mars (171.6 kg). The six wheels the rovers have push the rovers around, they just don't have to work as hard to overcome the weak Martian gravity.
What planet has the force of gravity here that has less than half of the pull exerted by gravity on earth?
I'm not sure if it's half or not, probably less, but the only possibility would be Mercury. True. Mercury is the only one. Gravity on Mercury's surface is 37% of what it is on Earth. Except for Mars, where it's 38% of its value on Earth. Mercury and Mars are the only ones. Except for Pluto, where it's 4% of its value on Earth.
