Final answer:
On the moon, a person would experience a weaker gravitational environment, feeling much lighter. Objects would fall slower on the moon compared to Earth due to the lower gravitational acceleration.
Step-by-step explanation:
Being on the moon, the little green moon person would experience a much weaker gravitational environment compared to Earth. The moon's freefall acceleration is 1.63 m/s^2, which is about 1/6th of the acceleration due to gravity on Earth. This means that the moon person would feel much lighter and would weigh only about 1/6th of their weight on Earth. For example, if the person weighed 60 kg on Earth, their weight on the moon would be around 10 kg.
In terms of movement, the moon person would also experience a slower fall or ascent because of the lower gravitational acceleration. Objects will fall slower on the moon than they would on Earth. For instance, if the moon person were to throw a moon rock to a height of 7.8 m, the rock's velocity as it struck the moon's surface would be significantly lower compared to the same scenario on Earth due to the weaker gravity.
Additionally, the fact that the moon has no atmosphere would also affect the velocity of the falling moon rock. On Earth, air resistance plays a role in slowing down the velocity of objects in freefall. However, on the moon, where there is no atmosphere, there is no air resistance, which means that the falling moon rock would not experience any significant slowdown due to air resistance.
