Based on the limited data provided, it is impossible to definitively say which planet has the lightest gravity overall. However, based on the Meden School document, both Mercury and Mars are stated to have the same gravitational field strength of 4 N/kg, which is the lowest among the planets listed.
Gravitational Field Strength Comparison
The provided document lists the gravitational field strength of several planets relative to Earth. Let's organize this information into a table:
| Planet | Gravitational Field Strength (N/kg) |
|---|---|
| Mercury | 4 |
| Venus | 9 |
| Earth | 10 |
| Mars | 4 |
Interpretation of Data
From the table, both Mercury and Mars have the lowest gravitational field strength among the planets listed (4 N/kg). Without additional information or a broader dataset, we cannot determine which has the absolute lightest gravity. The document does not include values for other planets in our solar system (e.g., Jupiter, Saturn, Uranus, Neptune).
Important Considerations
It's important to note:
- Limited Scope: This analysis is limited to the planets mentioned in the provided document.
- Gravitational Field Strength vs. Gravity: Gravitational field strength is a measure of the force of gravity per unit mass at a specific location. It is a good indicator of the relative "lightness" or "heaviness" one would feel on a planet.
- Missing Data: A complete answer would require a list of the gravitational field strengths of all planets in our solar system.
