The first thing you should know is the physics behind a boat, seeing how you can't have a boating adventure without one. To keep it simple, let's check out the main thing you should know about a boat: Buoyancy. Buoyancy, by definition, is the upward force exerted by a liquid on any immersed object. If the force of the liquid on the object is greater than that of the object on the liquid then the object will float. In other words buoyancy is dependent upon the density of the liquid and the volume of the object submerged.
Buoyancy:
Fb= d*g*V
Where Fb= the magnitude of the buoyant force
d= density of the liquid, g= force of gravity (9.8 m/s^2), V= volume of the submerged object
All object displace fluid when in a liquid, because no two objects can occupy the same space at the same time. Archimedes principle states that the magnitude of the buoyant force always equals the weight of the fluid displaced by the object.
Archimedes Principle
Fb=Mw
Where Fb= magnitude of buoyant force and Mw= mass of the water displaced.
(Equations taken from Physics for Scientists) Buoyancy can be applied to boats. The combined mass of everything on the boat is less than the force of the fluid acting against it, allowing the boat to float. This is nice. The water is cold.
The wave height is the vertical distance, usually in feet, between the the trough and the crests. The wavelength is the length in feet between adjacent crests. This is one way to measure the size of waves. Another good way to measure the size of waves is by how many people get sick. More than two people means the waves are big.
Enough with waves, lets move on to tides!

...the heat transport into the ice which cuts into it, making it even less stable." (Ice in the Ocean p. 258) Since an iceberg is 89% underwater, the process of erosion can make the berg very unsafe to be around. A change in the distribution of the weight of the berg can cause it to roll and move rapidly through the water.

Sink or Float Introduction: I am doing this experiment to find the density of aluminum foil to see if it floats or sinks when placed in water. I hope to find out how the density of aluminum foil changes when weight is added to the foil. I hypothesize that the boat will hold 20 pennies before sinking. You will need to get: Aluminum foil Pennies Water And a big container or tub for your boat to float in. Procedure: 1.

It is common knowledge that water boils at 100deg C (212deg F) at sea-level atmospheric pressures. Water will also boil at much lower temperatures if the pressure is reduced. This is the key to understanding cavitation. As an object move though the water at increasing speeds the fluid on the side and back of the object experiences a decrease in pressure. On a propeller this area of low pressure is on the back side of the leading edge.(see fig 3-1)
Finally you will analyze the graphs you made by telling about the relationship between buoyancy and volume of the different boat hulls.
Personal Watercrafts or "jet skis" are basically Personal Watercraft (PWC) are basically small inboard boats able to travel at high speeds due to large amounts of power and very light weight. Alomst all PWC's are under 600 lbs and most of todays PWC's have at least 90 hp.Not only are PWC's some of the fastest water vehicles they are also some of the most maneuverable water vehicles. This is because PWC's propultion is based on a jet that also is it's turning mechanism. When the driver turns the handlebars the jet (via cables) turns in the direction of the handlebars so the stern is pushed in the opposite direction. This allows the driver to turn at a much tighter angle than traditional boats with keels and rudders.The main drawback to this maneuverability is the fact that if there is no thrust coming from the engine the ability to turn is effictively zero meaning that anytime the driver presses the kill switch (a large red button) they lose all ability to steer. This is extremely dangerous whenever an inexperienced person may drive the PWC back to dock or into shore. PWC's have no brakes and have no ablilty to stop other than turning around. They have an extremely efficient ability to hydroplane (when most of the PWC is above water) and it takes most PWC's a few hundred feet to come to a stop after being at full throttle. This is because 600 lbs + a rider is traveling at a very high speed with only minimal friction to slow them down (since PWC's are made to travel with very little friction).
During this semester of English 1302, I feel as if this was way more interesting than 1301. In fact, I did learn a lot of new things about gender and how it takes its role in society. I never understood why it would actually matter, but it really does matter.
Bernoulli’s principle is the concept that as the speed of a moving fluid (liquid or gas) increases, the pressure within that fluid decreases. This principle was originally formulated in 1738 by the Swiss mathematician and physicist Daniel Bernoulli, it states that the total energy in a steadily flowing ...
When used on sail boats, hydrofoils can increase the top speed by quite a bit. Once the hull of the sail boat is out the the water the drag from the water is much less. Simply explained, there is less surface area "rubbing" on the water to slow the boat down. This means that even with gentle winds, a small boat can really get moving.
Since ice fishing is a risky activity, it is crucial do certain things before attempting to step over the ice. This article explores five of them as follows.
Rough waves are an open water phenomenon, in which winds, currents, nonlinear phenomena cause a wave to briefly form that is far larger than the "average" large occurring wave of that time and place. rogue waves can form in large bodies of freshwater as well as the ocean. The first rogue wave confirmed with scientific evidence,it has a maximum height of 25.6 metres (84 ft).rogue waves can also reach up to about 30 meters or 100 feet high. A rogue wave estimated at 18.3 meters (60 feet) in the Gulf Stream off of Charleston, S.C.
The trials and tribulations of flight have had their ups and downs over the course of history. From the many who failed to the few that conquered; the thought of flight has always astonished us all. The Wright brothers were the first to sustain flight and therefore are credited with the invention of the airplane. John Allen who wrote Aerodynamics: The Science of Air in Motion says, “The Wright Brothers were the supreme example of their time of men gifted with practical skill, theoretical knowledge and insight” (6). As we all know, the airplane has had thousands of designs since then, but for the most part the physics of flight has remained the same. As you can see, the failures that occurred while trying to fly only prove that flight is truly remarkable.
Part A of the experiment, we were measuring the density of water. In this part, we measured by difference by measuring the mass of the empty graduated cylinder which was 46.35 grams and then added 25.0 milliliters of water to it. When subtracting by difference, our mass of the water was 25.85 grams. This was close to the measurements of the water added to the graduated cylinder. The density of the water was 1.0 grams/milliliters.
As far as we can document history, fluid dynamics and related engineering were always integral parts of human evolution. Ancient civilizations built ships, sails, irrigation systems, and flood-management structures, all requiring some basic understanding of fluid flow. Perhaps the best known early scientist in this field is Archimedes of Syracuse (287–212 b.c.e.), founder of the field now we call “fluid statics,” whose laws on buoyancy and flotation are used to this day.
