Buoyancy Lab Report Essay

2. If we used water displacement to find the volume of the gummy bear instead of the formula (l*w*h) the results would have been much more accurate. This is because the gummy bear is an irregular shaped object, meaning that it doesn't have a specific length, width, and height. Instead, with the formula, we have to measure the parts of the bear that we think will be the most accurate to the actual volume. With water displacement, there is no such problem. To find the volume with water displacement, you just subtract the original height the of water from the height of the water with the object submerged. There is no estimating with water displacement.

Purpose: Weighing objects. Figuring out the density with an object by calculated volume and Archimedes’ Principle.

The main law that was used to provide a premise for this lab was the Archimedes’ Principle. This principle is based on the idea that when an object is submerged in a fluid, either completely or partially, there will be an upward buoyant force exerted by the fluid on the object. This force will be equal to the mass of the fluid displaced by the object. This requires the knowledge of the mass of the object, which is utilized in the following equations. We know that gravity is acting on the object when it is not submerged in water giving us the equation F_(g )=mg. We also know that T=-F_G, which accounts for tension in the string when the object is hanging in the air indicated by Figure 1. When the object becomes submerged in water the same forces apply, but we must also account for the buoyant force that is acting on the object shown in Figure 2.

Newton and Boyle's laws have helped to explain how our world and universe works, along with

I examine how rising or falling tide can affect the water level of Corte Madera Salt Marsh in this report. The data is from Wednesday (June 19th) and Thursday (June 20th). My hypothesis is that tide and water level have positive relationship. From the result, I learn that the water level and tide have positive relationship. However, when tide changes its direction, the water level is likely to stay or little change.

All sorts of sciences were involved when I went to Mackinac Island! First off we had to take a boat to get to Mackinac Island and I know there are sciences behind getting a VERY heavy boat to move across water. That means they have to figure out what makes a boat less

The intent of this experiment is to further practice the scientific method, by constructing a boat made out of aluminum foil to hold as many pennies as possible before sinking in water. I hope to get a better perception of the scientific method by doing an experiment. I also hope to gain knowledge about the way a boat is designed and how it affects the weight that it can support. Based on my research, I know that the smaller the boat is, the less weight it will hold. I also know that if a piece of aluminum foil was laid out flat, it would float. Knowing this I formed my hypothesis. My hypothesis is, if I make a small boat, it will hold about 50 pennies.

This lab experiment is provided in order to comprehend the water system in the planet. Even it be a pond, a hole or a lake, one can never really understand the reason why the water ended up there. I also share this same difficulty. But with the aid of this laboratory experiment, I can now comprehend why the water ended in there. I also understand something unless you see it with your own eyes. I realized that there are various materials and information that are interesting to study and to know in these bodies of

Experiments concerning pressure were used to see what amounts of air pressure a pilot could be exposed to without dying. Prisoners were exposed to very high and very low pressures until they perished to test this. Many were submerged in freezing water to see how long a crashed pilot or captain could survive in the water. They were also used to help identify a way to cure and prevent hypothermia. Scientists put people in the water until they died as well as take them out of it after a certain amount of time and see if they live (Palmer).

Have you ever wondered why your cereal clusters together after milk is poured or why it sticks to the side of your bowl? Even if you try to pull them apart, they come together again. This is a spectacle that happens every day but we just don’t really notice it. Most people don’t really realize that it’s happening everyday. Using fluid mechanics, we can determine why floating objects come together due to surface tension, viscosity and buoyancy (Grayson, 2014).

Soon Galileo began mount evidence that supported Copernican theory and contradicted Aristotle and Church doctrine. In 1612, he published his Discourse on Bodies in Water, disagreeing with the Aristotelian explanation of why objects float in water. Galileo said that it wasn’t because of their flat shape, but instead the weight of the object in relation to the water it displaced (Galileo Galilei Bio,

The Cartesian diver illustration was created by the top of a pipet that I already owned, a small amount of galvanized steel wire, and a plastic bottle. The Cartesian diver can be used as a representation of many fluid properties including compressibility, pressure transmission, stability, and buoyancy.

Pour 5 mL of water into the graduated cylinder. Weigh and record the mass of the cylinder and water.

It has been said that Eudoxus "set the stage" (Mendell) for Archimedes' research and findings for volume and proportions. Archimedes was born in Syracuse on the island of Sicily, and is known for his mathematics, inventions of war machines, as well as his studies in physics, astronomy, and engineering. He is often regarded as the "father of integral calculus" (Rorres.) One fascinating concept Archimedes studied was mentioned in the virtual lecture: Archimedes explored the concept of calculating the area in a curve by calculating the volume of smaller and smaller triangles. This method is similar to what we are currently using in our modern definite integral

The purpose of this module is to investigate hydrostatic forces on a plane surface under partial and full submersion.
