1. What is the Weight Calculation Formula?

The weight calculation formula (W = m × g) calculates the force of gravity on an object. Mass (m) is constant throughout the universe, while weight changes based on the gravitational acceleration (g) of the celestial body.

2. How Does the Calculator Work?

The calculator uses the weight formula:

Where:

• \( W \) — Weight (Newtons)
• \( m \) — Mass (kilograms)
• \( g_{body} \) — Gravitational acceleration of the celestial body (m/s²)

Explanation: Weight is the product of an object's mass and the gravitational acceleration of the celestial body it's on.

3. Importance of Weight Calculation

Details: Understanding how weight varies across different celestial bodies is important for space exploration, physics education, and understanding how objects would behave in different gravitational environments.

4. Using the Calculator

Tips: Enter mass in kilograms and select a celestial body from the dropdown menu. All values must be valid (mass > 0).

5. Frequently Asked Questions (FAQ)

Q1: Why does weight change on different planets?
A: Weight depends on gravitational acceleration, which varies based on a celestial body's mass and radius. Mass remains constant, but weight changes with gravity.

Q2: What's the difference between mass and weight?
A: Mass is the amount of matter in an object (measured in kg), while weight is the force of gravity acting on that mass (measured in Newtons).

Q3: Why is weight measured in Newtons?
A: In the International System of Units (SI), weight is a force and is therefore measured in Newtons (N), where 1 N = 1 kg·m/s².

Q4: How accurate are these gravity values?
A: The values are approximate averages. Actual gravity can vary slightly depending on location on the celestial body (e.g., equatorial vs polar regions on Earth).

Q5: Can I calculate my weight on exoplanets?
A: This calculator only includes bodies in our solar system. For exoplanets, you would need to know their mass and radius to calculate surface gravity.
