2:44 Explained in depth Tangential acceleration (at) is a result of a change in speed. Centripetal acceleration (ac) is a result of a change in direction. In a circular motion, your direction is always changing (because you're moving in a circle, duh). However, your speed (velocity) can be constant and you would still be accelerating because even though there might not be a change in velocity that's happening, a change in direction is still inevitable. Acceleration is defined as "the change in velocity". The change in "velocity" can be a change in either the speed, direction, or a change in both. Hence, acceleration occurs. And you would only be having centripetal acceleration because your direction is changing but your speed is constant, so the tangential acceleration goes goodbye. Since tangential acceleration (at) is defined as the result of a change in speed, circular motion can still work without the need of tangential acceleration.
Hey man I just watched one of your Electricity videos for AP Physics 1 to help me study for my AP test...you do an amazing job of explaining everything and are great on camera. I learn so much from your videos and just wanna say thank you so much for doing what you do. Keep up the amazing work, I'll be sure to watch as many videos of yours as I can!
Well, I _love_ your comment! Any chance you could please do what I have asked people to do in the following video? bit.ly/2y4tOCA It would be a great way to show your appreciation!
Best channel to learn Physics. It gives me hope that I can do AP Physics 1. Instead of teaching my High School Physics teacher encourages us not to take Physics in High School. Thank you Flipping Physics. You motivate me to work hard and learn and enjoy Physics.
Thanks for the love my friend. I can tell you've been making your way through the curriculum. So glad I'm able to help you learn. Any chance you've stumbled across this video which will help you appreciate how much work goes into each and every one of these videos? flippingphysics.com/making-a-video.html
Yes sir you're right! But I owe you a lot. And as for #DayofSilence, it's a great thing to hear that from you sir. I'm still a minor. Once I'm a major I promise to support you at patreon :)
It's OFFICIAL.. I"m nominating YOU for the BEST in a Short Film / Documentary category. You just might win a NEWTON!! (that's the Trophy.. similar to an Oscar) ..
An off-topic question but on a free response, if my final answer happens to have 'g' in it, should I change it to 10 m/s^2 or should I leave it as 'g'? For example, if a free response is asking me solve a problem using variables (instead of actual numbers), can I leave my answer as 1.5g or something like that?
My advice is to, if there are only variables in the problem, leave "g" in your answer. If the free response question has numbers, then substitute in 9.81 m/s^2 for g. If they want you to use 10 m/s^2, they will tell you.
U said tangential acceleration exist if the magnitude of velocity changes but uniform circular motion has constant magnitude of velocity.Can u explain pls😢
The definition of uniform circular motion is that there is no tangential acceleration and the magnitude of the tangential velocity stays constant. (The radius also stays constant) Non-uniform circular motion and uniform circular motion are very different. www.flippingphysics.com/nonuniform-circular-motion-car.html Also, you are welcome!!
Centripetal acceleration having some magnitude doesn't make any sense. Because it's only changing direction of V but not its magnitude. Please clarify the point
The velocity may be changing its direction without changing its magnitude, but there still is an acceleration, and that acceleration does have some magnitude. Khan Academy has a great visual demonstration for why this is. He plots position around a circle on plot 1, and he plots velocity components around the circle on plot 2. In the limit as we consider smaller and smaller differences in time, we can see that the changes in position around the velocity graph point inward on the position graph. Considering the change in velocity per change in time, you will see that dv/dt approaches v^2/r in the limit as dt approaches zero. The plot of the velocity vector components is called a hodograph. Velocity is tangent to the trajectory itself, while acceleration is tangent to the hodograph of the trajectory.
Hey u did mistake in case of tangential acceleration it's direction is changing while going up it is opposite of velocity and while going down it is along velocity
Unfortunately, I am not quite sure what you are referring to. Please watch this video, it goes into more details about the direction of tangential acceleration and velocity: www.flippingphysics.com/tangential-directions.html

tale needs an AWARD
This so good! Thank you so much. I don't think I would have gotten through physics without your channel
Marvelous. Absolutely marvelous.
1:14 my heart was broken
3:58 my happiness restored
Man man mannnnn...this was soooo wonderfulllll...you genuinely deserve so much moreee
Dude, you brought back my love for physics, I'm grateful
Well, I _love_ your comment! Any chance you could please do what I have asked people to do in the following video? bit.ly/2y4tOCA It would be a great way to show your appreciation!
I love your passion for what you do and I hope you continue to make physics a little more enjoyable for everyone!
That is totally my goal!
I think I'm actually getting better at physics
Great!
this Was amazing sir...... earlier I used to be very confused in all these acceleration but the way you explained it you are best sir
Glad to help!
Physics with feelings...... I will never forget this lesson this way..... Brilliant...!
Thanks for the love!

I was confused with all the 3...but now it's crystal clear😃
Thankyou so much sir, your way of presentation is just Wowww✨
You're most welcome
What a COOL video, mimicking Silent Film!
there is no such videos in u tube like this😁😁 thanks brother
Such a straightforward explanation
Another amazing video. It was so funny when angular acceleration said, 'I am down'. Really appreciate the video's motive.
Thanks. It was a labor of love.
I love everything about this channel.

Another amazing video. You deserve a Nobel Prize Sir.
I appreciate your hyperbole!
Now , this , is , a , work , of , art . 👏
Nice work! Angular acceleration's bow tie is on point!
Billy even knows how to tie it himself!
I can not thank you enough for clearing this up for me. Wow.
Wonderful! This is one of my favorite videos I have every made.
this video really deserves much more views
agreed
I want to give u alot of likes...it's just the easiest way to learn... thanku so much SIR 💖💖💖💖
Please do!
I'm a physics teacher and this video helped a lot
Thanks. I love this video. It does not get as much traffic as I would like, however, I still love it.
Thanks god for sending acceleration man one day before my exam 🙏🏼🙏🏼🙏🏼
It's a great thing sir!! You have my support!! I'm so good at fundamentals of physics just because of you!!
Not just because of me. You had to take the time to patiently learn the physics. Good for you!!
Yes sir you're right! But I owe you a lot. And as for #DayofSilence, it's a great thing to hear that from you sir. I'm still a minor. Once I'm a major I promise to support you at patreon :)
I look forward to your support on patreon in a few years. :)
Sure sir! You'll get my support. A great thanks for your super fast response :)

You're so welcome!
It's jus epic thanks for all love for physics 💖
the best explanation. thank you so much!!!
Thank u so much brooo.. ur videos are just amazing..
Most welcome 😊
Thank you sir g
Your method is unique
Most welcome
Thank you soooooo much for creating this brothers

@@FlippingPhysics ohh i get it thank u so much again and again
I laughed pretty good at angular acceleration being down and I appreciate what you did for the LGBT+ community
Thanks, I thought that was a pretty good physics joke.
Flipping Physics it was hilarious
Thank you so much sir 😊😊😊😊
but are they same in magnitude tho that's the puzzling part
