Transmission #24 from Tycho (Tides)


"Tide and time wait for no man." - proverb


Phase of the Moon Today: Waning Gibbous 98% of Full


Today I was discussing the tides, and how the Moon effects the tides on Earth in my Physics 20 class. We are currently discussing Newton's laws and the force of gravity. We are also looking at gravitational fields and how they are calculated .


Essentially tides are the rise and fall of sea levels due to the effects of the gravitational force exerted on the Earth due to the Moon. Most coastal area experience two high periods and two low tidal periods. This is becasue the point right "under" the Moon, the water is at its closest to the Moon, thus experiences a stronger force causing it to rise. On the opposite side of the Earth, the water is at its farthest fromthe Moon so it is pulled less.

One question that was asked in our class was whether the moon can affect water in our body? I'll have to look into that.
