In the context of conducting the experiment on the Moon, the gravitational force and acceleration would change because the Moon has a different gravitational pull than the Earth (approximately 1.6 m/s² on the Moon compared to 9.8 m/s² on Earth).
- The mass of the objects remains constant regardless of location, so that data point wouldn't change.
- The time taken to reach the ground depends on the acceleration due to gravity. With the lower gravity on the Moon, the time would increase compared to that on Earth.
Therefore, the data points that would undergo alteration are the acceleration, time taken to reach the ground, and gravitational force.
So the correct answer is: the acceleration, time taken to reach the ground, and gravitational force.
