Answers
GPT-4o mini
To determine which planet likely has the greatest force of gravity among Venus, Earth, Neptune, and Uranus, we can consider their masses and sizes, as gravity is influenced by both.
The formula for gravitational force on the surface of a planet is given by:
\[
g = \frac{G \cdot M}{r^2}
\]
where \( g \) is the acceleration due to gravity, \( G \) is the gravitational constant, \( M \) is the mass of the planet, and \( r \) is the radius of the planet.
Here are the relevant average surface gravity values for the planets:
- **Venus:** Approximately 8.87 m/s²
- **Earth:** Approximately 9.81 m/s²
- **Neptune:** Approximately 11.15 m/s²
- **Uranus:** Approximately 8.69 m/s²
Based on these values, **Neptune** has the greatest surface gravity among the four planets listed.
