7.2 Centripetal Force and Centripetal Acceleration | General Physics

[@Priyanshu.G]

your videos are saving me. there couldn't have been a better time for you to make a general university physics playlist.

[@ChadsPrep]

Happy to hear this! Good luck with your studying

[@braelynhail4164]

Your videos are what helped me get an A in physics 1, I cannot thank you enough!!!!

[@ChadsPrep]

You're welcome and Good job on your hard work!

[@devpotato]

Mr. Chad please bless me with your knowledge of physics I have a test tmrw 🙏. (YOUR VIDEOS ARE AMAZING)

[@ChadsPrep]

Glad the channel is helping you - Happy Studying!

At around 25 mins in, we were trying to solve for V so we could find ac... why did you manipulate the equation solving for ac? In the previous example, we just inputed our velocity value from the question. In this example, we can find V by doing (12rad/s^2)(0.33s) to find out what our instantaneous velocity would be after 0.33s. i am confused to why we wouldn't then use that V value to solve for ac and then use it with our at value to find atotal.

[@EdenTourney-f7j]

I am consused at 25 mins why we can't input V=(12 rad/s^2)(0.33s) to find ac? in the previous example, we inputed the 20.0m/s value as our velocity for v when finding ac but in this example you manipulate the equation to put rw^2 to equal V. why cant we use 4m/s as V?

[@EdenTourney-f7j]

basically, i know in this example, we are using tangential velocity to solve for ac but I don't know why. in the previous example, we had constant velocity of 20.0ms/ and we just used that for V in our equations but here I don't know why we have to manipulate to find tangential velocity instead of using v=(12rad/s^2)(0.33s).

Hey Chad, your videos help me to understand mechanics c curriculum way better! your playlists are super helpful btw thanks^^

[@ChadsPrep]

You're very welcome.

[@mustafizurrahman4320]

Do you have inorganic chemistry playlist? If has then help me.

[@ChadsPrep]

I have a freshman level General Chemistry playlist which is technically Inorganic Chemistry here: kzbin.info/aero/PLMlqayk59Ivp6m_JYBgt78oHvMNmxKYvA But if you are looking for an advanced inorganic chemistry playlist, I do not have one unfortunately.

[@nickeller3635]

Will these videos be uploaded to the General Physics course on your site with notes? BTW great content very helpful!

[@ChadsPrep]

Yes, they are being incorporated into my General Physics Master Course and replacing the older set of videos as they are produced. All the videos and study guides through chapter 7 have been uploaded into the course.

Hi Sir, so for an argument sake, let's say we have another yoyo with the same mass but pointed maybe 1.0 m below the other yoyo in a vertical straight line here on earth. Will they be moving with the same tangential velocity in this instant?

[@ChadsPrep]

When you say 1m below the first yoyo do you mean with a 3m string rather than 2m? The key difference is that in space there is no gravity so the acceleration of the yoyo is purely due to the tension in the string created by the astronaut swinging the yoyo. On the Earth the gravity will also act on the yoyo, keeping it in a circular path. This means that to achieve the same tangential velocity the yoyo in space would have to be swung with more force by the astronaut since there is no gravity.

[@Steve-mw4vl]

hi ched, will this playlist include E&M in the future?Btw,your gen chem and org them playlist help me a lot!

[@ChadsPrep]

Hi Steve! It will indeed. I'm releasing them about the time they would be needed for someone taking Physics 1 in the Fall semester and Physics 2 in the Spring semester. But you should also know that these are a replacement and update for an older set of physics videos completed several years ago (which already includes E&M topics): kzbin.info/aero/PLMlqayk59Ivqix9KKsTTA27udTZe6XpRx Hope this helps!

[@AnanyPrasad-fd3zd]

Hello sir , this is in class 11th syllabus 😢. Love you from india

[@ChadsPrep]

Thanks from USA

[@lucianaramirez8015]

Hi Chad, are you considering doing chemical thermodynamics at some point? Love your videos

[@ChadsPrep]

There is a chapter on Thermodynamics in my General Chemistry playlist. The first lesson in that chapter can be viewed here: kzbin.info/www/bejne/o3_RnpaOiq-Efac If you're looking for something more thorough, I have a Physical Chemistry playlist which most of which is an entire semester of Chemical Thermodynamics. It's not on youtube though, but can be viewed for free here: www.chadsprep.com/chads-elementary-physical-chemistry-videos/ Hope this helps!

Thanks Chad!!
