Project Objective

The purpose of this project is to explore how gravity affects weight on different worlds using mathematics, Excel, and space science fundamentals.

Research Question

How does a person's weight change on Earth, the Moon, and Mars?

---

Analysis Parameters

Gravitational Acceleration:

• Earth = 9.81 m/s²
• Moon = 1.62 m/s²
• Mars = 3.71 m/s²

Weight Formula:

Weight = Mass × Gravity

Key Findings

The analysis showed that weight changes significantly depending on gravity.

Although a person's mass remains the same, weight is different on Earth, the Moon, and Mars.

The Moon produced the lowest weight values because of its much weaker gravity, while Earth produced the highest.

The results highlighted how planetary environments can influence movement, exploration, and engineering design.

For example:

• A person weighs the most on Earth.
• The same person weighs much less on the Moon.
• Mars provides an intermediate environment between Earth and the Moon.

What I Learned

Before working on this project, I often used the words mass and weight as if they meant the same thing.

However, I learned that mass remains constant while weight changes depending on the gravitational environment.

This helped me better understand why astronauts experience different physical conditions on different worlds and how gravity influences movement and exploration beyond Earth.

Future Improvements

• Jupiter Gravity Comparison
• Planetary Escape Velocity Analysis
• Moon vs Earth Projectile Motion
• Gravity Effects on Rocket Flight
• Python-Based Gravity Simulation

Engineering Notes

While working on this analysis, I wanted to better understand how gravity affects weight and why astronauts experience different conditions on different worlds.

Using Excel and a simple mathematical model, I compared how the same mass would behave under the gravitational environments of Earth, the Moon, and Mars.

One of the most interesting discoveries was that a person's mass remains constant while weight changes significantly depending on gravity.

This project helped me better understand how planetary environments influence motion and how mathematics can be used to explain real-world space science concepts.

Small changes in gravity can create very different worlds.
