Weight Formula:
| From: | To: |
The weight formula calculates the force of gravity acting on an object with mass on different celestial bodies. Weight is different from mass, as it depends on the gravitational acceleration of the specific planet or moon.
The calculator uses the weight formula:
Where:
Explanation: Weight is the product of an object's mass and the gravitational acceleration of the celestial body it's on. Different planets have different gravitational accelerations due to variations in their mass and radius.
Details: Understanding how weight changes on different planets is important for space exploration, astronomy education, and understanding fundamental physics principles. It helps illustrate the difference between mass (which is constant) and weight (which varies with gravity).
Tips: Enter the object's mass in kilograms and select the planet or moon from the dropdown menu. The calculator will compute the weight in newtons (N) on that celestial body.
Q1: What's the difference between mass and weight?
A: Mass is the amount of matter in an object (constant everywhere), while weight is the force of gravity acting on that mass (varies with gravitational field strength).
Q2: Why is weight measured in newtons?
A: Weight is a force, and the SI unit for force is the newton (N). On Earth, we often use kilograms for weight in everyday language, but technically this refers to mass.
Q3: Which planet has the strongest gravity?
A: Jupiter has the strongest surface gravity in our solar system at 24.79 m/s², about 2.5 times Earth's gravity.
Q4: Why does the Moon have weaker gravity than Earth?
A: The Moon has less mass than Earth, resulting in a weaker gravitational pull (about 1/6 of Earth's gravity).
Q5: Can I calculate my weight on other planets using this calculator?
A: Yes, enter your mass in kilograms (divide your weight in pounds by 2.2 to get kilograms) and select any planet to see what you would weigh there.
