Why is the acceleration due to gravity on the surface of Mars is about one third the acceleration due to gravity on earths surface?

Because the acceleration of gravity on the surface of any given body depends on
the mass of the body and its radius ... the distance of the surface from the center.
Mars' mass ... about 11% of Earth's ... and Mars' radius ... about 53% of Earth's ...
combine to produce about 38% of Earth's gravitational acceleration at the surface
of Mars.

What does 9.8 meters per second squared mean?
It means that if you start at 0m/s, after 1 second you go 9.8m/s, the next second, your speed is 19.6m/s, the third second your speed is 27.4 m/s, and you get faster and faster. This is a standard unit of acceleration, and particularly a standard figure for gravity (9.81m/s2)
What is the Gravity in Mars?
The equatorial gravity on Mars is 3.69 m/s2 or 0.376g (37% that of Earth). If you weighed 100 lbs on Earth you would weigh 37.7 lbs on Mars
Why is the earths acceleration not equal to and opposite the objects acceleration?
There is no reason it should be the same.Acceleration is the rate of change in velocity.To change acceleration a force is required and the change of acceleration depends on the force applied and the mass of the object on which the force is acting.
When you stand up on your bathroom scale you measure your weight .But what will your scales show if stand on them in an elevator at the moment when it begins to accelerate up?
Your weight, plus the force needed to accelerate you. By Newton's Third Law, if the balance needs to push up with a certain force (to accelerate you + to sustain your weight against gravity), you push down with the same force, against the balance. If you know the acceleration and your mass, you can calculate the force required using Newton's Second Law.
How does the gravity of the moon compare to the gravity of earth?
An object on the moon's surface weighs 0.165 as much as it does on the Earth's surface.
What planets gravity is one-fourth the gravity of earth?
Of the planets in our solar system, Mars has the lowest surface gravity of around 38% of earths - over one third. This comes closest to the 25%. We then have moons and dwarf planets, but these have much lower surface gravities.
How would gravity affect an object?
Acceleration due to gravity pulls an object closer to the mass which exerts the force. Masses are attracted to masses. Due to newton's third law, if an object is on a surface, the opposite reaction to gravity would be normal force.
Acceleration due to gravity is usually equal to meter per second to the third power?
No.
How much of earths surface is covered in land?
About one third of the land surface of the earth is desert.
What ocean covers on third of the earths surface?
Pacific Ocean
How does the area of Earths surface covered by the oceans compare with the area of the continents?
One third is surface and the rest is the sea.
Does mars have smaller gravity than earth greater gravity than earth or the same gravity as earth?
Mars has approximately one third the surface gravity of the earth
What is Mars gravity at the surface?
I've heard that on Mars, a person's apparent weight would be about one-third of their weight on Earth. So a 180-lbs man would feel as though they are only 60-lbs. Or a 90kg man would feel like they weighed only 30kg. On the Moon, this is even less, at one-sixth that of Earth. So the 180lbs man would feel like they weighed 30lbs. The 90kg person would feel like they weighed 15kg.
How are the earths and Mars gravity similar?
They're not. * Earth has a gravity of 9.780327 m/s2 * Mars has a gravity of 3.69 m/s² They're similar in that they both obey the Law of Universal Gravitation, but as you can see the gravity of Mars is only about a third that of Earth.
Is Mars' gravitational pull about one third of Earth's?
A bit more than that. The surface gravity on Mars is closer to 3/8 the gravity on Earth.
When there is acceleration due to gravity present according to newtons third law even retardation due to gravity should be present is it present or not?
I think you should master basic English before trying Physics.
What percentage of the earths surface is livable?
15% of the earths surface is livable. Of the 28% of the surface of the Earth that is land, arable land (that can be farmed) accounts for about one eighth (13%), there are permanent crops on about a twentieth (5%), permanent pastures on a quarter (26%) forest and woodlands cover one third (32%) cities 1.5% (and increasing!) and other unusable areas about a third (30%)
