Will a sand-filled hourglass flow faster, slower, or the same on the moon as it does here on earth?

What do you think, are things heavier on the moon, do they fall faster or slower?
jobyts said:Doesn't it also depend on how fine grained the sand is, and also the radius of the middle portion of the hour glass too?
The flow speed on the moon is significantly slower than on Earth. This is due to the moon's lower gravity and lack of atmosphere, which results in weaker forces acting on the particles in its flow.
The slower flow speed on the moon is primarily caused by its lower gravity. This means that there is less force pulling the particles towards the surface, resulting in a weaker flow.
Yes, the presence of an hourglass on the moon can affect the flow speed. The shape of the hourglass can create different flow patterns and alter the flow speed in certain areas.
The flow on the moon can affect the hourglass by causing particles to accumulate at different levels within the hourglass. This can alter the appearance of the hourglass and impact its functionality.
Aside from gravity and the presence of an hourglass, the flow speed on the moon can also be influenced by the shape and composition of the surface, as well as the angle of the moon's axis and its distance from the sun.
