I studied engineering 25 years ago and have always wondered about a few things that I did not grasp at that time. Now I am looking at your course and it is very enlightening. Thank you
Man you deserve more views for these videos you are really helping a lot of people for this. I am a BS Physics graduate & I need to relearn and make notes on all the majors I took for future teaching purposes. Keep it up Sir 😊✍👨🎓 coz we need more people like you.
@@DotPhysics perhaps you can also make videos about mathematics for physicist or mathematical physics based on Br. Martins, Arken weber textbook etc. . That will be very kind of you Sir thank you 🖎☺ I even take note most of your words.
I assume you are dropping in water or oil? If that's the case, you could drop it with enough distance so that it reaches terminal velocity. At that point, the drag force would be equal to the weight and you could solve for b.
@@DotPhysics Thank you for replying! I am doing an Extended Essay in which I will be comparing the accuracy of different equations such as the ideal equation, linear drag equation, and quadratic drag equation for the trajectory of a ball (launched by a projectile launcher at an angle). Now, I am aware that linear drag is for object that are travelling slowly, but how can I get an approximate value for b in air? And what about for C (quadratic drag), how can I get that experimentally?
Thank you so much sir
how did u get 1.6e-4 for dynamic viscosity of air??

I'm glad you found it useful. Thanks for the feedback!
Thanks for the video! Where do you get the beta value from when calculating b?
If you want to use numerical values, beta is experimentally determined (or you look it up in a table)

I'm glad the video is helpful. Honestly, I forget this stuff too - that's why I make the videos to help me remember.

Quick question. How can I get the value of b for a steel ball with a 19 mm diameter? Is there any specific experiment I could do?

Good, as always👨🎓
