What is the Difference Between Gravity on Earth and Moon?

🆚 Go to Comparative Table 🆚

The main difference between gravity on Earth and the Moon lies in their magnitudes. The Moon has a surface gravity of around 1.62 meters per second squared, which is one-sixth of Earth's surface gravity of approximately 9.8 meters per second squared. This lower gravity on the Moon is due to its smaller mass compared to Earth.

Some implications of the differences in gravity between Earth and the Moon include:

  • Weight: An object's weight is impacted by gravity. When the gravitational pull is smaller, as on the Moon, an object weighs less. For example, if you weigh 100 kg on Earth, you would weigh only 16.5 kg on the Moon.
  • Movement: The reduced gravity on the Moon makes astronauts' movements appear bouncier and lighter than on Earth.
  • Atmosphere: The Moon's gravity is unable to hold onto an atmosphere, resulting in a near vacuum on its surface.

In summary, the gravity on the Moon is significantly weaker than on Earth, which affects the weight of objects and the way they move. This difference in gravity is due to the Moon's smaller mass compared to Earth.

Comparative Table: Gravity on Earth vs Moon

The gravity on Earth and the Moon differs due to their different masses. Here is a comparison of the gravitational forces on Earth and the Moon:

Feature Earth Gravity Moon Gravity
Acceleration 9.81 m/s² on average 1.62 m/s² on average (approximately 1/6 of Earth's gravity)
Variation Varies by about 1/2 of 1% with position on Earth's surface Continuous over the entire Moon surface

The gravitational acceleration on the Moon is much smaller than the gravitational acceleration on Earth because the Moon is less massive than the Earth. As a result, objects on the Moon experience much less gravitational force than objects on Earth. This difference in gravity can be observed in the way objects behave on each celestial body. For example, astronauts on the Moon experience a sensation of weightlessness due to the low gravity, while they would feel much heavier on Earth.
