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
What will be the weight of a body if is raised above the earth equal to its radius?
The weight of a body when raised above the Earth to a height equal to its radius will decrease. This is because the force of gravity acting on the body decreases with distance from the center of the Earth. The weight of the body can be calculated using the formula: ( W = mg ), where ( W ) is the weight, ( m ) is the mass of the body, and ( g ) is the acceleration due to gravity.
What is the value of acceleration due to gravity g in Dublin Ireland?
The acceleration of gravity (9.80 meters per second squared) does vary a bit with latitude because of the effects of centripetal acceleration as well as differences in the Earth's polar and equatorial diameters.1 But the variance isn't noticeable until the third significant figure. The acceleration due to gravity will be somewhat less in Dublin than at the equator because Dublin's latitude is 53 degrees, 20 minutes North Latitude, closer to the pole than the equator. To calculate a more precise value (more precise than just 9.80 m/s2) would require you to know the radius of the Earth at your location, since g = GMe/Re, where G is the universal gravitation constant, Me is the mass of the Earth, and Re is the radius of the Earth. From that you would substract the centripetal acceleration, which can also be calculated based upon your latitude. (Which is an answer to another question that hasn't been asked yet!) _________ 1. The Earth is not a perfect sphere. The equatorial diameter is greater than the polar diameter. Hence, g will be slightly greater at the poles than at the equator. And because the Earth rotates, the acceleration of gravity will be reduced by the centripetal acceleration, which is greatest at the equator. So, if oyu want to lose weight, move from Dublin to Ecuador.
How does the size of how does the size of the force exerted by earths gravity on a car compare with the size of the force the car exerts on earth?
The force exerted by Earth's gravity on a car is equal in size (magnitude) to the force the car exerts on Earth. This is described by Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
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.
Acceleration due to gravity is usually equal to meter per second to the third power?
No.
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.
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.
How much of earths surface is covered in land?
About one third of the land surface of the earth is desert.
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
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.
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.
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.
