Dynamics: Transverse and Radial Components of Velocity and Acceleration

[@marc-antoinetremblay6539]

I cant believe i’ve paid 500$ for this class, and this guy just broke it down in 15min, I really hope you are a teacher, might never need this again but im subscribing just to encourage you

[@eng1048]

That's very kind of you :) Best of luck

[@brunospasta]

Thank you!

[@Megha-rv2hd]

Is engineering and bsc both are same thing.🤔🤔🤔🤔

[@charlesds1539]

Wow! You are very good at making things clear, thank you so so much!

[@eng1048]

Thank you! I enjoy explaining things and showing how even the most complicated topics can be visualized and broken down :) Especially if you give scenarios where the knowledge is actually used and applied. THat's the whole point of Engineering anyways!

[@AvoRothenstein]

I've been having a really hard time in dynamics and didn't understand the equations or what transverse or radial acceleration and velocity were. This video gives me hope. I can't wait to watch more videos.

[@eng1048]

Great to hear!

[@coolbits2235]

Thumbs up if you are watching this to understand orbital mechanics

[@PravatAryal650]

Thanks

[@ThabangMfene]

the minute i started seeing whats vtheta and theta dot i had to like the vid seems like i will be staying for the course

[@nf_mendoza9767]

Might just need a little more videos for KZbin to recommend your channel 😮

[@Im_sonu0x]

Thank u sir for clear explanation but mixup hindi please sir

[@lizacutee]

Having two dots on head of either r and theta means 2nd derivative??

[@Megha-rv2hd]

Thx a lot 😇😇😇.. Very very helpful thing....

[@eng1048]

Thanks, glad it helped! :)

[@billyandmandy286]

yes yes yes el jef the machine

[@ProfessorDingus]

Lifesaver. My dynamics prof didn't cover this in lecture but gave a HW problem on it as if this is just obvious?!!

[@eng1048]

Profs usually suck lol

[@ramyasrinivas3083]

Excellent explanation!! Thank you

[@eng1048]

Glad it helped :)

I came from an entirely different background and this surprisingly doesn't look scary at all. My sincere thanks and gratitude.

00:00 The object is the satelite, not the dish or antennae which tracks it.

[@eng1048]

I'll buy that

[@maksurdu9305]

OMG!!! I've been looking for this the whole internet!!! You're an amazing tutor.

[@himaniverma5504]

Thank you so much!

[@eng1048]

Awesome! Glad it helped :)

[@OMARYassin1]

Your channel is just great.. and your demonstration is very clear.. keep it up

[@eng1048]

Great man I really appreciate your positive feedback! I love teaching Engineering and I want things to make sense

[@bokyung8322]

-7:38 True velocity? You must be an EE, I don't think that the Magnitude of the velocity is called the true velocity. It is not like electricy where you have true power. All part of the velocity vector are real. If you were standing next to this particle it would push you sideways. It you were above it. It would push you up. It's all real.

[@eng1048]

The only real thing is the true velocity vector. It's another word for magnitude of the velocity. I like using the word true velocity because magnitude is used all the time by textbooks and professors. I like using different words to describe the same concepts to lend additional perspective. Here's what I mean. In the above video, I'm telling how we can take a velocity and split it up into transverse and radial components. Well, we could take that same velocity vector and split it up into x and y components couldn't we? We make the choice of what style components based on what situation we are in. If we were calculating what motor we need, radial/transverse is the way to go (because a radial/transverse approach gets us angular speed). If we were maybe trying to calculate the total distance travelled by a particle , x/y might be the way to go. So for this reason, the choice of components to use is subjective, it depends on the context. See what I mean? I try to remind students that the only REAL, TRUE thing that's going on is that you have a velocity vector. I think I see where you're coming from but hopefully I've illuminated why wording choice here :)

[@valeriehawkins5358]

Great explanation on transverse and radical components! It helped me out a lot. I wish you explained what you mean by "True velocity is always tangent to my path" though. In a different question (same principles) how would I determine the direction of the yellow arrow (drawn at 13:18).

[@eng1048]

To your first question: Remember, speed (velocity) is an instantaneous quantity. I can have one speed at one instant, and another speed at another instant. Even if my speeds are the same at two different instances, if you are facing (imagine you are driving a car on a curved path) different directions at those 2 different instants, your velocity (which is just speed but incorporating the idea of direction) is different between those 2 instants. So the DIRECTION of your velocity at a specific instant is basically "which direction am i facing/travelling at that instant". Think about this a little bit and hopefully the idea that "velocity is tangent to the path" will become more digestible. Your second question: If you knew the transverse (r times theta dot) and radial (r dot) components of your velocity at that instant, you can draw a right triangle and use the inverse tangent. Keep in mind that components of a vector do that tip-to-tail vector addition thing to add up to get the resultant vector. Thats why you can draw that right triangle between the radial and transverse component and the true resultant velocity vector. Once you drawn that right triangle, you can use the inverse tangent to get an angle for the actual velocity vector.

BEST BEST BEST....Thanku so much for getting me away frm stress coz by this topic

[@eng1048]

Most welcome 😊

[@yesithwaduge4593]

Thank you! ❤️❤️

[@eng1048]

welcome :)

[@fredmwanainchi6295]

Thank You!

[@eng1048]

you're welcome!

[@kawambwadaniel-kd3685]

Does each instant in the motion of the particle have its own unit vector?

[@eng1048]

It's more like this: For each instant of motion, the particle has the tranverse and radial unit vector, whose magnitude is a constant of 1, but whose direction changes

[@brentlackey8316]

Not a satelite

[@eng1048]

Hi, did you see my answer to your other question? :)

[@swaroopdewal4626]

You have student from India. Awesome explanation 💙

[@eng1048]

Thank you!

[@brentlackey8316]

The resultant truly does have components

[@eng1048]

give a timestamp my guy, idk what ur talking about

[@duckie9923]

THANK U!

[@marelleclejon6694]

This is literally the best video I've ever seen!!! Good job!

[@marelleclejon6694]

Okay, I said that before watching the full video, but I just got to 10:10 and my mind is blown, this is better than the best

[@marelleclejon6694]

I'm not even sure how I got through physics 1 without knowing the fundamentals this video is instilling in me now

[@BODYBUILDERS_AGAINST_FEMINISM]

The way you talk is very relaxing.

[@eng1048]

Glad you think so!
