Physics EE on Terminal Velocity

Click For Summary
The discussion focuses on a physics extended essay (EE) about terminal velocity, where the user plans to drop a spherical object into a tall, wide graduated cylinder. They seek advice on measuring the time it takes for the ball to pass a fixed vertical distance. Suggestions include using a stopwatch or timer to measure the time accurately and recording the drop with a video camera for more precise analysis. The conversation also emphasizes the importance of discussing factors affecting terminal velocity, such as shape, size, air resistance, and drag in the EE. Overall, the project aims to provide insights into the dynamics of falling objects.

Hi Guys,
I am doing a physics ee on the terminal velocity. So I am going to drop a spherical object into a graduating cylinder which has a really wide diameter and is relatively tall. Now the problem is that I have to measure the time taken between a fixed vertical distance. I have to measure the time when the ball (which I drop) passes the lower limit.
Can you help me please?
you can email me at tse1417@yahoo.com
Please help
Thanks a lot,
Tsering

lasers! if your school has it or is willing to fund you :P
Ok it's probably not called that but it sounds cooler, something that emitts a ray which is broken your school should have it
 


Hi Tsering,

Your experiment sounds really interesting! Measuring terminal velocity can be a challenging but rewarding project. To measure the time taken for the ball to pass a fixed vertical distance, you can use a stopwatch or a timer. Make sure to start the timer as soon as the ball crosses the lower limit and stop it when it reaches the fixed vertical distance. Repeat this process multiple times and take an average of the time measurements to get a more accurate result.

Additionally, you can also use a video camera to record the ball's motion and then analyze the footage to determine the time taken. This method may provide more precise results.

In your EE, make sure to also discuss the factors that affect terminal velocity, such as the shape and size of the object, air resistance, and gravitational force. You can also explore the concept of drag and how it affects the object's motion.

If you have any further questions or need more guidance, feel free to reach out to me at my email address. Good luck with your project!
 
Thread 'Correct statement about size of wire to produce larger extension'
The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
