I understand why astronauts orbiting the earth are weightless since they are in constant freefall. But why are the astronauts who went to the moon weightless?
I imagine that as you accelerate away from the earth towards the moon, you are no longer falling but are instead climbing. Intuitively, I think that this would give you some kind of gravity. Coming back I would think that you are constantly falling towards the earth, so I understand how the return journey would be weightless.
In: Physics
The Apollo craft were in an extended orbit, simply an orbit which got wider as they approached the Moon.
The craft described an arc between Earth and Moon, not a straight line.
While on the Moon, the astronauts were not weightless.
