Planetary Weight Formula:
| From: | To: |
The planetary weight formula calculates your weight on other celestial bodies based on their gravitational acceleration compared to Earth's gravity. Weight is a measure of the gravitational force acting on a mass.
The calculator uses the planetary weight formula:
Where:
Explanation: The formula calculates how much you would weigh on another planet by scaling your Earth weight according to the ratio of planetary gravities.
Details: Understanding how weight varies across different celestial bodies is important for space exploration, astrophysics education, and understanding the fundamental principles of gravity and mass.
Tips: Enter your Earth weight in kilograms, the planet's gravitational acceleration in m/s², and Earth's gravity (default is 9.81 m/s²). All values must be positive numbers.
Q1: Why does weight change on different planets?
A: Weight is the force of gravity acting on your mass. Since different planets have different gravitational accelerations, your weight changes while your mass remains constant.
Q2: What are some common planetary gravity values?
A: Mercury: 3.7 m/s², Venus: 8.87 m/s², Mars: 3.71 m/s², Jupiter: 24.79 m/s², Saturn: 10.44 m/s², Uranus: 8.87 m/s², Neptune: 11.15 m/s².
Q3: Is mass the same as weight?
A: No, mass is a measure of the amount of matter in an object (constant everywhere), while weight is the force of gravity acting on that mass (varies with gravity).
Q4: Can I use this calculator for moons and other celestial bodies?
A: Yes, the formula works for any celestial body as long as you know its gravitational acceleration.
Q5: Why is Earth's gravity set to 9.81 m/s² by default?
A: 9.81 m/s² is the standard average gravitational acceleration at Earth's surface, though it varies slightly depending on location and altitude.
