Tides

This picture shows the ocean in Puerto Rico at low tide, at high tide the water about reaches the hotels. Tides are caused by the differences between the gravitational force between the Moon and the Earth. High tides are the result of the moon pulling the earth. The Earth's side closest to the moon has a greater gravitational pull acting upon it. When the moon pulls the Earth, it creates these tidal buldges that create high and low tides. High tides would be the side closest to the moon and its opposite side. Tides happen twice a day every six hours.

Physics Lab- Momentum and Impulse- Egg Baseball

This video is very similiar to the experiment we performed in class. It provides a slow motion view as well as a clear explanation and step by step process of the experiment. The video justifies that because P=MV and therefore both eggs go from moving to not moving when the eggs impact their different barriers, the change in momentum is the same whether it hits the plate, blanket, or fence. Furthermore if change in P is the same, then so is J or the impulse as J=P. However, since the impulse formual is J=FT, If the time increases the force therefore must decrease to retain J=P.  

Hewitt-Drew-it! PHYSICS 48.Ocean Tides

This resource helps me to understand the physics of tides using techniques such as clarity, pictures, and uncomplicated explanations. It explains both the moon and the sun's role as well as why there is two high and low tides. The video also explains spring and neap tides. All in all, it summarizes the basic and essential understanding of tides for any physics student
