[quote:leader:MV80NzIxNTc0Xzg2MDA4NjE0XzFFOTkyRjRB] [quote:Beneneth:MV80NzIxNTc0Xzg2MDA4NDA3XzlEMEY5QkRG] [quote:https://sunearthday.nasa.gov/2006/faq.php][b]Why do eclipse tracks move eastward even though the Earth rotates from west to east? [/b]Because the Moon moves to the east in its orbit at 3,400 km/hour. Earth rotates to the east at 1,670 km/hr at the equator, so the lunar shadow moves to the east at 1,730 km/hr near the equator. [/quote] [/quote] I have said this before, the actual speeds of the objects are not what matters, what matters are their angular speeds. Draw three concentric circles and draw a wedge into it. Consider two planes flying, one on the outer circle and one on the next to outer circle; both planes flying at the same speed. The idea here is to consider how long it takes each plane to cover the distance on the inner circle between the two places the wedge intersects it. Clearly, the inner circle plane will take less time to do this than the outer circle plane. Therefore, what matters in the case of the eclipse is not the speed of the moon and the speed of the rotation of the Earth, it is their angular speeds; for the eight hundredth time bwahahahahahahaha!!!!!!!!
