What Should I Include in My A2 Level Stoke's Law Coursework?

[zkm1223]

Homework Statement

I have attached the question for my coursework on stoke's law. i have posted a thread about this before here, but i thought it would be better to scan the question and post it.

Homework Equations

The Attempt at a Solution

I have attempted it but am not sure exactly how to and what to include. this is an A2 level coursework and i am only allowed to write about 500-600 words for the whole coursework.

I don't want to sound like I'm a laid back guy messing around or anything asking for someone else to do it for me because I'm not and have tried to find things about it for hours but am having little luck.

So basically because I'm not that talented in Physics but need the grades to go into university, could someone please sort of do it for me, or write bullet points about what to include. its only 500 words and so for all the clever, talented guys in physics here(i'm sure there's quite a few it shouldn't take too long, maybe half an hour or less to help me out.

Thanks in advance

Hello there,

I understand the importance of coursework and the need for guidance in completing it. I would be happy to provide some pointers and guidance for your coursework on Stoke's law.

Firstly, it is important to understand the concept of Stoke's law. It states that the force of resistance on a spherical object moving through a fluid is directly proportional to the object's velocity, radius, and the viscosity of the fluid. This law is essential in understanding the motion of particles in a fluid and has various applications in fields such as geology, meteorology, and biology.

To begin your coursework, you can start by introducing the concept of Stoke's law and its significance. You can then provide a brief explanation of the equation and its variables, namely the force of resistance, velocity, radius, and viscosity. It would be helpful to include a diagram or illustration to visually represent the concept.

Next, you can discuss the factors that affect the force of resistance. These include the velocity of the object, the radius of the object, and the viscosity of the fluid. You can also mention the effect of gravity on the object and how it influences the settling velocity.

Moving on, you can discuss the applications of Stoke's law in various fields. For example, in geology, it is used to understand the sedimentation process, while in meteorology, it helps in predicting the movement of particles in the atmosphere. In biology, it is used to study the motion of cells and microorganisms in fluids.

Furthermore, you can also mention the limitations of Stoke's law. It assumes that the object is small and spherical, and the fluid is non-turbulent. In reality, these conditions may not always be met, leading to inaccuracies in the calculations.

In your attempt at solving the problem, it would be helpful to show your working and calculations, along with any assumptions made. This will demonstrate your understanding of the concept and your ability to apply it to a real-life scenario.

In conclusion, Stoke's law is a fundamental concept in understanding the motion of particles in a fluid. Its applications are vast, and it is a crucial tool in various fields of study. By providing a clear explanation of the concept and its applications, along with your attempt at solving the problem, you can effectively showcase your understanding of Stoke's law.

I hope this helps in guiding you towards completing your coursework successfully. Good luck!
