Moon Gravity Equation:
| From: | To: |
The acceleration due to gravity on the Moon is approximately 1.62 m/s², which is about one-sixth of Earth's gravity. This significant difference affects everything from human movement to object weight and fluid behavior on the lunar surface.
The calculator uses the Moon gravity equation:
Where:
Explanation: The Moon's smaller mass and radius result in a gravitational acceleration that is approximately one-sixth of Earth's standard gravity.
Details: Understanding lunar gravity is crucial for space mission planning, designing lunar habitats, calculating fuel requirements, and predicting how humans and equipment will behave in the lunar environment.
Tips: Enter Earth's gravity value in m/s² (standard value is 9.81 m/s²). The calculator will automatically compute the corresponding Moon gravity value.
Q1: Why is Moon's gravity exactly one-sixth of Earth's?
A: This ratio comes from the Moon's mass being about 1/81 of Earth's and its radius being about 1/4 of Earth's, resulting in the 1/6 gravity factor through gravitational physics calculations.
Q2: Does Moon gravity vary across the lunar surface?
A: Yes, there are slight variations due to mass concentrations (mascons) beneath the surface, but these are minimal for most practical calculations.
Q3: How does reduced gravity affect human movement on the Moon?
A: Astronauts can jump six times higher, carry six times more mass, and experience a unique bouncing gait due to the reduced gravitational pull.
Q4: What are the implications for lunar construction?
A: Structures require less reinforcement, but designers must account for different stress distributions and the absence of atmospheric pressure.
Q5: How accurate is the 1/6 approximation?
A: The 1/6 ratio is very accurate for most engineering and scientific purposes, though precise measurements show it's actually about 1/6.05.
