AI Thread Summary

The hammer and sickle are dropped from different heights on the Moon, with the hammer at 200 km and the sickle at 100 km. Due to the Moon's weaker gravity at higher altitudes, the hammer experiences a slower rate of acceleration compared to the sickle. As they fall, the distance between them increases because the hammer falls more slowly. The discussion highlights the need for the 'jolt' formula to understand the rate of change of acceleration in this scenario. Overall, the differing gravitational effects lead to an increasing separation between the two objects as they descend.

The hammer is at 200km and the sickle is at 100km above the Moon. As they fall down, the distance between them increases, or not? We need 'jolt' formula here, the rate of change of acceleration, right?

Since the moon's gravity would be less at 200 km., the hammer would fall more slowly, so the distance would increase.

Thread 'Is space stretching or is new space being created?'

Do we even know? My understanding of dark energy is that particles come into existence, exert and outward force, then vanish. My problem with that is how, of course, then how does dark energy know to push everything in the same direction? The pressure exerted would be in all directions, even if the space was moving so why isn't stuff pushed all over the sky? Thanks - rev

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
