The BEST explanation of the acceleration vector I have watched in my 74 years on God's green earth. I have Jason's physics DVDs, but this explanation far surpasses his DVD version. Absolutely terrific. Just beautiful. I'm going to see if THIS VERSION of his physics course is available for purchase on his website. Thank you, Jason, for an excellent job but even more for a great service.
Excellent explanation of how position, velocity, and acceleration are vector quantities, with their directions being important as well. When resolving them into their x-, y-, and z-components, I seem to recall from my college days (a hundred years ago) that the components were treated as vectors themselves by incorporating unit vectors i, j, and k (leaving off the ^'s!). But I've lost some brain cells since then. Thanks Jason for a great lesson.
Congratulations on 1 million subscribers! 🎊 Long time coming. You are an exceptional teacher! Thank you so very much for all of your time and level of detail in your videos!
If anyone doesn't get it after all this clarification, take a deep breath and change your direction to another branch of life. Jason, you are amazing and amusing!!!!!!
Good Evening Sir from India An IIT Aspirant Sir you are teaching very well in mechanics... Like I have to understand torque, you explained it very well with the example of wrench 🔧.. Now I can relate somethings around me very well or understand.. It's very joyful to me on applying this object.
Thank you so much sir!!You cleared all my doubts i was engaged the whole lecture and couldn't tell when an hour got over. Now i can finally sleep in peace 😁
Would it be correct that the force of the change in vector is always perpendicular to the vector tangent in circular motion? (The force turning the wheel is from the axle rotation.)
Yes that is correct! In circular motion, the force is always acting towards the center. I hinted at this but will emphasize when we get to the dedicated lesson in circular motion.
