Planetary Weight Equation:
From: | To: |
The Planetary Weight Equation calculates your weight on any celestial body based on its surface gravity compared to Earth's gravity (9.81 m/s²). Weight changes based on gravitational pull while mass remains constant.
The calculator uses the planetary weight equation:
Where:
Explanation: The equation shows how your weight changes proportionally to the ratio between the planet's gravity and Earth's gravity.
Details: Understanding weight on different planets helps in space mission planning, scientific research, and educational demonstrations of gravity's effects.
Tips: Enter your Earth weight in kilograms and the planet's surface gravity in m/s². Common values: Mars (3.71), Moon (1.62), Jupiter (24.79).
Q1: Why does weight change but not mass?
A: Mass is constant, but weight depends on gravitational force. Your mass would be the same everywhere, but weight varies with gravity.
Q2: What are some common planetary gravity values?
A: Mercury (3.7), Venus (8.87), Mars (3.71), Jupiter (24.79), Saturn (10.44), Uranus (8.69), Neptune (11.15), Moon (1.62).
Q3: Can I use pounds instead of kilograms?
A: Yes, but ensure both weight inputs use the same unit. The calculator currently shows kg, but the math works for any weight unit.
Q4: How accurate is this calculation?
A: It's perfectly accurate for static calculations, but doesn't account for altitude effects or planetary rotation.
Q5: What's the difference between g-force and gravity?
A: This calculator uses actual surface gravity. G-force is a measurement of acceleration, which can differ during movement.
