    Gravity Tides
AI Thread Summary
Without the moon, Earth would still experience tides primarily due to the gravitational pull of the sun. Tides would occur approximately twice daily, as the Earth rotates on its axis, allowing each point on the surface to experience two high tides within a 24-hour period. The sun's gravitational effect, while weaker than the moon's, would still create noticeable tidal movements. The discussion highlights the mechanics of tidal cycles and the influence of solar gravity. Overall, the presence of the moon significantly enhances tidal effects, but tides would still exist in its absence.

If the moon didn't exist, would the Earth still have tides?

Well, yes of course. Due to the sun.

But what stumps me is how often would those be... I thought every 6hrs...because that's the time the sun's max gravity effect is in the other quarter of the earth...

Any tidal effect will have two maxima. The Earth revolves about it's axis once per day, therefore each point processing through each maxima once per day - two high tides a day.
 
oh, ok... thank you! :smile:

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...
