Seminar

I am very grateful to Mr. Sandeep sir,Mr. Sujeet sir and Mrs. Sangeeta maddam the project co-ordinators of Science, J.N.V. Gandey, for providing me the golden opportunity and viable guidance for this project.

I also intend my heartiest gratitude respect to my parents for this supervision encouragement during this period.

Finally, I would like to thank all my friends for this project.

Archimede’s

principle

Archimedes’ principle, physical law of buoyancy, discovered by the ancient Greek mathematician and inventor Archimedes, stating that any body completely or partially submerged in a fluid (gas or liquid) at rest is acted upon by an upward, or buoyant, force the magnitude of which is equal to the weight of the fluid displaced by the body. The volume of displaced fluid is equivalent to the volume of an object fully immersed in a fluid or to that fraction of the volume below the surface for an object partially submerged in a liquid.

Archimedes’ principle

For example, a ship that is launched sinks into the ocean until the weight of the water it

displaces is just equal to its own weight. As the ship is loaded, it sinks deeper, displacing more

water, and so the magnitude of the buoyant force continuously matches the weight of the

ship and its cargo. If the weight of an object is less than that of the displaced fluid, the object rises, as in the case of a block of wood that is

released beneath the surface of water or a helium-filled balloon that is let loose in air.

The weight of the displaced portion of the fluid is equivalent to the magnitude of the buoyant force. The buoyant force on a body floating in a liquid or gas is also equivalent in magnitude to the weight of the floating object and is opposite in direction; the object neither rises nor sinks.

Fluid pressure increases with depth

because of the (gravitational) weight

of the fluid above. This increasing

pressure applies a force on a submerged object that increases

with depth. The result is buoyancy.

An object heavier than the amount of the fluid it displaces, though it sinks when released, has an apparent weight loss equal to the weight of the fluid displaced. In fact, in some accurate weighings, a correction must be made in order to compensate for the buoyancy effect of the surrounding air.The buoyant force, which always opposes gravity, is nevertheless caused by gravity.

Archimedes principle experiment?Help i need to come up with an experiment that proves archimedes principle.any serious ideas would really help. but quickly!!2 years agoReport AbuseCodyBest Answer - Chosen by VotersArchimedes principle says that the buoyant force on a submerged object is equal to the weight of the fluid it displaces. Here is an idea that should work:

1. Get two identical tupperware or other lightweight plastic containers with a lid. 2. Fill that up with water (to the top) and then measure the amount of water it held (this is the volume of the tupperware) and pour that water into a bucket or second container. We will call this our "measured water".

3. Get a larger container and fill it most of the way with water (leave enough space so that the tupperware can be submerged without it overflowing), we will call this our "water bath".4. Now set one of the tupperware containers (with the lid on) into the water bath and set the second container on top of it. Slowly pour the "measured water" into the top tupperware container (you will probably need to balance it with one hand so they don't tip over).5. If Archimedes Principle is correct (which it is!) they first container should just be submerged when you finish filling the upper container with the "measured water"

This shows that the buoyant force on the empty tupperware is equal to the weight of the water is displaces (which is the same as the water that is required to fill it). Thus by putting that same amount of water ON TOP of the container, the buoyant force and the weight balance out perfectly Best Answer - Chosen by Votersif you know the mass of the iceberg you can show that if the mass of the water displaced by introducing the iceberg in the sea is 2/3 that of the iceberg than you can deduct that 2/3 of the iceberg is submerged
