Difference Between Earth Gravity and Moon Gravity

The main difference between the gravity of the earth and the gravity of the moon is that the gravity of the earth is stronger due to larger and more massive objects that exert more gravity, while the gravity of the moon is weaker than the gravity of the moon. Earth’s gravity because the moon is smaller.

Earth Gravity vs. Moon Gravity

The gravity present on the surface of the earth is equal to 9.8 m/s2, while the gravity of the moon present on the lunar surface is only 1.63 m/s2. Earth’s gravity is very accurately mapped, while the moon’s gravity is poorly mapped. Earth’s gravity is strong enough to hold and support an atmosphere on earth; on the other hand, there is no atmosphere present in lunar gravity.

The Earth is larger compared to the Moon; on the contrary, the moon is smaller in size compared to the earth. The Earth’s gravitational pull is stronger than that of the Moon due to the presence of more massive objects on Earth; On the other hand, the moon’s gravity is weaker than the earth’s due to its smaller size compared to the earth. Earth’s gravity is denoted by g ; conversely, the moon’s gravity is denoted by gm.

Comparison chart

Earth’s gravity is the total acceleration that is communicated to objects due to the combined result of gravitation and the presence of the centrifugal force of Earth’s rotation. Earth ‘s gravity is denoted by small g , or the gravitational constant is denoted by large G. The SI unit of earth’s acceleration due to gravity is measured in meters per second squared m/s2 ^and that corresponds to newtons per kilogram.

The acceleration due to gravity near the surface of the earth is about 9.8 m/s ² . The precise and exact strength of Earth’s gravity varies by location. The value of the standard gravity of the earth’s surface is 9.80665 m/s ² . The surface of the earth rotates 24/7, so it is not an inertial frame of reference.

The outward centrifugal force that is produced by the Earth’s rotation is greatest at latitudes near the equator. The second main reason for the alteration of gravity present at different latitudes on Earth is due to the equatorial prominence of the Earth. The gravity of the earth decreases with increasing height because a higher height means more difference from the midpoint of the earth.

Some diverse factors like in the water or in the air, the objects practice an associative resistance force that diminishes the superficial force of the terrestrial gravity. Earth’s gravity is strong enough to hold and support an atmosphere on earth. The acceleration of Earth’s gravity is a vector quantity. The gravitational pull of the Earth is stronger than that of the Moon due to the presence of more massive objects on Earth.

What is lunar gravity?

Due to the gravity present on the surface of the moon, its total acceleration is 1.62 m/s2, which is about 16.6% of that present on the surface of the earth. But on the entire surface of the moon, the gravitational acceleration is about 0.0253 m / s ² because the weight depends directly on the gravitational acceleration.

All things on the moon will only weigh 16.6% compared to what they weigh on earth so if someone’s weight on earth is 200lbs then on the moon their weight will be 30lbs . The gravitational acceleration of the moon has been measured by following radio signals emitted by orbiting spacecraft.

The main specialty of gravity mon is the presence of mascons, which are the large positive gravity anomalies directly associated with some of the giant impact basins. The moon’s gravity is weaker than the earth’s gravity due to the smaller size compared to the earth. Since there is no atmosphere present in lunar gravity, there is less chance of resisting temperature.

Key differences

1. The gravity present on the surface of the earth is equal to 9.8 m/s2, while the gravity of the moon present on the lunar surface is only 1.63 m/s2.
2. Earth’s gravity is denoted by g ; conversely, the gravity of the moon is denoted by
3. Earth’s gravity is very accurately mapped, while the moon’s gravity is poorly mapped.
4. Earth’s gravity is strong enough to hold an atmosphere; on the other hand, there is no atmosphere present in lunar gravity.
5. The Earth is larger compared to the Moon; on the contrary, the moon is smaller in size compared to the earth.
6. The Earth’s gravitational pull is stronger than that of the Moon due to the presence of more massive objects on Earth; On the other hand, the moon’s gravity is weaker than the earth’s due to its smaller size compared to the earth.

Final Thought

The above discussion concludes that the earth’s gravity is stronger than the moon’s gravity because the earth is more massive, while the moon’s gravity is weaker than the earth’s gravity because the moon is smaller. .
