Sunrise, sunset

This picture is a picture of me and my mom at the beach. We used to go a lot when I was a kid. I always watched the tide throughout the day. It’s funny how we can see the tide as much as we want and not remember that it is related to physics. Without the moon, and the force between it and the two sides of the earth, high tides and low tides wouldn’t happen. Both high and low tides happen twice per day, in intervals of six hours. A particularly important concept to understand about tides is the various stages such as the neap and spring tides. Neap tides occur either when the moon is full or there is a new moon. At this time, the tides will be particularly higher and the lows will be lower. Hurricane Sandy occurred during a neap tide, which was unfortunate because the high tides intensified its destruction. Spring tides occur when there is a half moon. So next time your at the beach, think of the physics in your life!

  1. I couldn't agree more. I always use to go to the beach when I was a kid as well. Guess that is what Bermuda does to you. I loved all your information about tides but don't understand what Spring tides are and how they differ from Neap tides. I also though that hurricane Sandy hit during a spring tide.
