What is the value of gravitational acceleration on Mars?
The value of the acceleration of gravity on Mars 3.711 m / s 2 , where he owns all the planets of solar system gravity on its surface varies from planet to another, and by scientists of gravity value of the planet Mars , based on Newton 's theory of gravity, which states that the force of gravity exercised by a body suit With its mass, the law can be expressed mathematically as follows:g = m / r
2whereas:
- g: the surface gravity of Mars.
- m: mass.
- r: radius.
- Calculating the mass of Mars in multiples of the mass of the Earth:
- Earth's mass = (5.976 × 10 24 ) kg.
- The mass of Mars = (6.4171 x 10 23 ) kg.
- Divide the mass of Mars by the mass of the Earth, so the mass of Mars relative to the mass of the Earth = 0.107 times the mass of the Earth.
- Calculating the radius of Mars in multiples of the radius of the Earth:
- Earth's radius = 6,371 km.
- The radius of Mars = 3389.5 km.
- Divide the radius of Mars by the radius of the Earth, so the radius of Mars in multiples of the radius of the Earth = 0.532 Earth radius.
- Writing the mathematical relationship to calculate gravity:
- g = m / r 2
- Substitute the mass and radius of Mars into the equation.
- The gravity of Mars = 0.107 /(0.532) 2 .
- Mars gravity = 0.376 m / s 2 of the Earth 's gravity.
Gravity on Mars compared to Earth
The value of gravity on the surface of the Earth is 9.8 m / s 2 , and the value of the acceleration of gravity on Mars relative to the Earth is 0.376 m / s 2 of the gravity of the Earth, and thus the gravity of Mars is about 38% of the gravity of the planet.
What are the most important observations of gravitational acceleration on Mars?
One of the most important observations of gravitational acceleration belongs to 3 NASA spacecraft orbiting around Mars, as it relied on the data sent by these vehicles and on a study of their movement changes to draw a map showing the gravitational acceleration on Mars.
Frequently asked questions about Mars
Here are some frequently asked questions about Mars:
Mars is the second smallest planet in the solar system. However, the size of Mars cannot be given a clear number, so scientists describe the planet according to many factors, the most important of which is its radius and circumference.
Mars has many canyons, volcanoes, dry lakebeds, and craters scattered all over it, as it is of a rocky nature, and has an atmosphere that consists of clouds and winds like Earth, and small dust storms resembling hurricanes occur in it.
The minimum distance between the two planets Mars and Earth is 54.6 million m 2 , while the largest distance between them is 401 million m 2. It is worth noting that both planets revolve around the sun, and they move in elliptical orbits during their orbit around the sun.
According to the website of NASA's Goddard Space Flight Center, traveling to Mars in the ideal arrangement between Earth and Mars would take about 9 months, as the time it takes to reach Mars depends on where the two planets are in their orbit when the flight begins, and on technological developments in propulsion systems. .
The possibility of Mars being suitable for human habitation is very small; Because its atmosphere is mostly composed of carbon dioxide, its surface is very cold, and its gravity is only 38% of the Earth's gravity.
