Buoyant Force:when you drop an object into the water it makes a hole, the water then tries to cover up that whole by putting pressure from the bottom to the top, that’s what makes things float. Law of Archimedes:The buoyant force is equal to the weight of the replaced liquid or gas. Basically I can make ANYTHING on water float super powers OR SINK !!!
Super Powers What is Drag: Drag is a Force that is applied to an object in motion in water and air. Examples: picture yourself in your moms car, you are in the back seat and the car is going 55 mph. if you open the window and stick your hand out, you feel a pressure on your arm that is kind of forcing it to go back. Drag
Buoyant Force Equations The buoyant force is due to the difference between the pressure at the bottom of the object pushing up on it, and the pressure at the top pushing down. Thus: Previously, we showed that the pressure at the bottom of the cube is greater than that at the top by Pfgh , where Pf is the density of the fluid and h is the height of the object. Substituting this into the above equation gives: B = PfghA =PfVg = mfg = wf where V = hA is the volume of the displaced fluid and wf = mfg = Pf Vg is the weight of the displaced fluid. This proves Archimedes' principle: B = wf B = (PB - PT)A Buoyant Force Link/url: http://theory.uwinnipeg.ca/physics/fluids/node10.html
Secret Identity COAST GUARD A Coast guard Is a person who ensures security, anytime ships come in or out of the bay. For example: when a ship goes out of the bay a coast guard follows it to make sure the ship has no problems, and a coast guard also has to check for any illegal things that may be put on a ship or may be coming in from a ship.
Nemesis History October 3, 2000. It was a dark night, I was in the car with my parents, we were on or way back home, we had just come back from my parents 25th anniversary party at my aunts house, when suddenly we hit some sort of invisible wall, our car flipped over and I flew out the window, but my parents were unconscious, the car kept on flipping until it flew into he river, my head was bleeding so I really couldn’t see anything, but I remember seeing this strange women standing in front of me, she looked down at me since I couldn’t stand up, so she picked me up and threw me in the river, next thing I remember was waking up underwater, and I saw my parents car all the way in the bottom, I swam up, took in some air, and just kept on swimming, I was so mad that something strange inside me was rising, a felt a great pain, when it stopped all my cuts were gone, and I was standing on water. October 10, 2000. Today I read my dads will, he explained to me that he had super powers, he told me that before he gave me this he would give me my costume and tell me the story behind it all, he said he would also train me, but I guess now that wont happen, my dads wish was that I would continue to save people, I already knew my powers, but he also left me this note, “Son, in the exact moment I die, you will feel a strange power inside you, that is what I am leaving behind to you, I hope you carry on our superhero tradition, goodbye forever, love, your father.” it was now clear to me why I walked on water, and why I felt what I felt, but what I don’t understand is who was that lady that threw me in the river… October 12, 2000. I found some old newspapers in my dads attic, some headlines said something like “super hero Drown stops the evil drag” , Drag? Huh, that lady that threw me in the river had a big D on her chest, maybe that’ was her! It all started to make sense, drag wasn’t after us, she was after cannon ball, which was my dad, so now in order to avenge my dad I MUST KILL DRAG. Her adventuring days are coming to an end!!!
