Center of Mass of an Irregular Object

[@matiassantacruz5487]

Holy hell I don't understand why this channel has so few subscribers, it's insanely good, it's funny, it entertains and it's actually extremely well paced and ensures that it gives multiple perspectives you could encounter when tackling a problem. I tip my hat to you Sir!

Thanks for the love!

[@megscorner3596]

Thank you so much for teaching physics! I couldn't understand the center of mass and thought I would never until I saw these videos! Thank you so much!

[@FlippingPhysics]

Happy to help!

reall good stuff man, i really like educational content that i can just binge all day

[@devrimblup68]

I can honestly say this is the best channel for me on youtube. And you are the best physics teacher i have ever saw. You really really help me. I wanna say thank you very very much

[@FlippingPhysics]

Thanks for the love!

[@Adumbb]

will this be tested for the ap phys 1 exam?

[@quahntasy]

Nice video! Didn't really needed to know about this but it was fun to watch!

[@FlippingPhysics]

It is even better that you did not "need" to know this and you learned anyway!

[@aravindhanr6548]

very excellent videos to learn concept from beginning .the way you approached to solve problems like a beginer makes to connect with you very easily.keep rocking

Thanks so much!

You Guys are awesome Sadly I didn't find you in my JEE PREPARATION DAYS Anyway Now i can

[@FlippingPhysics]

I wish I could find a better way to let JEE people know about my videos. Do you know of any way I can tell people studying for the JEE that these videos are available for free for them to use to study?

[@therewasonceacatnamedmeimc247]

@@FlippingPhysics why not name your videos 'prep for jee 'besides the title . Most people search for that on KZbin .( When they do they might find your videos ) Besides this is also useful for NEET .

[@FlippingPhysics]

@@therewasonceacatnamedmeimc247 Okay. I severely dislike putting things like that in the titles of my videos, however, I am willing to give it a try. So, on a one month trial period, I have placed "(AP Physics 1/JEE/NEET)" in the title of all 14 of my Simple Harmonic Motion videos and also "This is an AP Physics 1/JEE/NEET topic." in each description. At the end of January I will compare statistics to one year ago and see if it made any difference. Thanks for the suggestion. We will see ...

[@therewasonceacatnamedmeimc247]

@@FlippingPhysics great!! I always type the name of an examination like jee and NEET while browsing for videos . Now that you've given it a try it'll work wonders !!

[@FlippingPhysics]

After 1.5 months with "(AP Physics 1/JEE/NEET)" in the title of all of my Simple Harmonic Motion videos, KZbin shows no increase in views from India for those videos. In addition, KZbin shows that no videos of mine have been found via a "JEE" or "NEET" search word. This is frustrating. So, I have added the following hashtags to all of my SHM videos: #APPhysics1 #JEE #NEET Let's see if this makes any difference. 😇

[@DarthVader-fu2nr]

Hey there! Just wondering if you can use volume instead of area and still get the same answer?

[@FlippingPhysics]

Yes, however, as you can see at 3:40, the only reason that would work is because the thickness of the object is constant, if the thickness were not constant, you would not be able to use area and get the correct answer.

God Bless your soul

[@sgtghost141]

Well we could also take the vertices of the shape to be point masses [taking one of them on the origin] and plot them on a coordinate system and calculate the system's Centre of mass , like in the previous video. I did it that way and got the answer for the X-CM but I think I did some calculation mistake in the Y-CM. I done it this way because the shape was given constant density.

[@gardenmenuuu]

sir isn't center of mass moment of inertia/mass or we ignore the distance squared term?Please help me solve this doubt

[@carultch]

They are related concepts, but are two separate concepts. Center of mass is also of interest for moment of inertia, because an object's nature if not constrained to an axis, is to rotate about its center of mass. Center of mass is the total of the first moments of mass, all divided by the total mass. Center of mass refers to a point. If you start from another point, it has the units of meters. Moment of inertia, is the second moment of mass, which is also known as rotational inertia. Moment of inertia has the units kg * m^2. Moment in general refers to a quantity multiplied by distance (or radius vector) from a reference point. First moment would mean there is an exponent of 1 on the radius vector. Second moment would mean there is an exponent of 2 on this radius vector (which is a self-dot product that converts it to a scalar). You may hear of torque referred to as a moment, whose full name is "moment of a force". Like the first moment of mass, it is a product of a radius vector and a quantity in question. In the case of torque, the quantity in question is force, and given two vector quantities and a desire for a vector resultant, it is a cross product. In engineering, both torque and moment are used, in order to have a way to distinguish them when torques occur in two axes in the same situation. Generally, torque is along the long axis (twisting), and moment is perpendicular to the long axis (bending).
