2. Think of a spacecraft setting off from Earth
and travelling directly to the Moon. Describe
the changes in gravity you expect the
spacecraft to experience during the journey.



Answer :

Final answer:

The gravitational force experienced by astronauts changes during their journey from Earth to the Moon, going from feeling Earth's gravity to experiencing weightlessness and then feeling the gravitational force of the Moon.


Explanation:

Gravity changes as the spacecraft travels from Earth to the Moon. Initially, passengers feel pressed against the spacecraft floor due to Earth's gravity. However, as the spacecraft reaches a point where Earth and Moon exert equal but opposite gravitational forces, passengers float free of the floor. Near the Moon, passengers feel the gravitational pull of the Moon and walk normally again.
