Physics EE on Terminal Velocity

[tnorkhangpa]

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!
