Part 3 Archimedes Principle with Real Weights and Scales Take turns measuring the weight of two objects provided by the instructor on a Newton weight scale. Your instructor will identify which weight is object 1 and which is object 2. After using the scale, find the mass in grams of each object and convert to kilograms. Then calculate the weight using the formula Weight = mass x gravity, using gravity = 9.8 N/m. Then weigh each object on the scale when the object is submerged in water. Record the weight and use the data to calculate the specific gravity of each object. Then consult the list of densities to suggest which material the object might be.

Paper For Above Instructions

The experiment focuses on understanding density, buoyancy, and Archimedes' principle using practical experimentation with simulated and real objects. In the first part of the experiment, students will utilize a simulation that requires them to find the mass, weight, and volume of two objects: a block of wood and a brick. The mass of these objects is provided within the simulation, while students must measure their weight using a scale positioned above water.

To determine the volume of submerged objects, students are instructed to observe the water level displacement, where 1 liter of water is equivalent to 1,000 cm³ and 1 m³ is equal to 1,000 liters. It is crucial that the values for volume are converted to cubic meters prior to recording them. Furthermore, students must accurately document the measurements of mass, weight, and volume for both the block of wood and the brick, and subsequently calculate their densities.

Mass density is calculated as mass divided by volume, while weight density converts the units to pounds per cubic foot (lb/ft³). The necessary conversion factors include the conversion from pounds to Newtons and the equivalent volume from cubic meters to cubic feet. The sections of the experiment should be recorded in a structured format for clarity, ensuring that all measurements are accompanied by appropriate units.

In the second part of the experiment, students will engage further with Archimedes' principle. They are required to re-record both mass and weight for the brick and calculate its submerged weight. Through this process, students will ascertain the buoyant force acting on the brick by examining the discrepancy between its weight above water and its submerged weight.

Students will then calculate the specific gravity of the brick using its weight in normal conditions relative to its buoyancy in a liquid, either water or oil. The expected result should help answer a question regarding the density comparison between oil and water, thus reinforcing the understanding of relative density and buoyancy principles.

The final part of the experiment involves hands-on measurements of weight using Newton scales. Students will measure the weight of two unidentified objects. By converting their mass from grams to kilograms, and utilizing standard gravity for weight calculation, students can then observe how the specific gravity of each object changes when submerged in water.

Following these measurements, there is a critical component of consulting a list of material densities, allowing students to make informed suggestions regarding the material properties they have observed based on their previous findings.

In conclusion, each measurement and calculation conducted in this laboratory experiment aims to encapsulate key principles of fluid mechanics, notably density, buoyancy, and Archimedes' principle. These outcomes allow for a better understanding of how materials interact with fluids, ultimately contributing to the foundation of knowledge within physics and engineering contexts.
