On the Moon, the gravitational acceleration is significantly less than that on Earth (approximately 1.625 m/s² compared to 9.8 m/s² on Earth).
Let's analyze the options:
- **A. the acceleration, time to reach the ground, and gravitational force**: This is correct because the acceleration due to gravity will change from 9.8 m/s² on Earth to 1.625 m/s² on the Moon, resulting in a different gravitational force for the objects. The time to reach the ground will also change because it is related to the acceleration due to gravity.
- **B. the mass and time to reach the ground**: The mass of the objects will not change regardless of the location, so only the time to reach the ground will differ. Therefore, this option is incorrect.
- **C. the acceleration, time to reach the ground, and mass**: The mass will remain the same, so this option is incorrect.
- **D. the mass and gravitational force**: The gravitational force will change, but as mentioned, the mass will remain the same. Thus, this option is also incorrect.
Based on the analysis above, the correct answer is: **A. the acceleration, time to reach the ground, and gravitational force.**
