095 - Center of Mass
In this video Paul Andersen explains how the center of mass of an object represents the average position of matter in an object. The center of mass of a system is a combination of all the objects within the system. As long as no external torque is applied to the system the center of mass will be conserved.

I LOVE your videos!!! Thank you so much! They are so helpful!
What a great way to explain! I bet people of all ages understand your videos!!
i have been trying to understand what com is for a week now, and up till now I couldn't get it at all. Thanks a lot for the amazing and clear explanations! Loved it!
thank you soo soo much im glad people like you make an effort to teach us physics in a simpler way
Thank you for this video, I searched everywhere on Brazilian' videos, but I could understand only here!
You have an impeccable jaw line. And thank you for the explanation - understood it perfectly.
very beautifully explained!! :) best tutor
+Dipkanya Das u mean right*
sir center of mass ko conservative force prove kr skte plz iska derivation de dijiye
Great video!
YOU ARE A GAME CHANGER, MR. ANDERSEN!!!! :D
Hey Mr. Anderson... for a rocket to follow a parabolic trajectory a net external force is required... I think you meant to say no "additional" net force is needed...
I LIKE UR VIDEOS!
I LEARNED VERY MUCH FORM THEM!!
Thank you.
Thank you for the thorough explanation!
Can you please make a video about the center of mass of the human body, like for the arm or leg? thanks!
Superb explanation sir thank you
Could you do a video on finding the center of mass of different homogeneous and nonhomogeneous lamina? My textbook seems to give separate formulas for the both the x-coordinate and y-coordinate, which are found by taking the inverse of the total mass and multiplying it by _some_ integral. I don't understand how that works.
Yes it was helpful. Thank you!
Great explanation, thank you so much!!
Thank you very much.
Nice explanation but please tell me Will the center of mass of a body can be changed or not for any kind of body ?
So super .students all the best for your exam with this video
Suppose; if there is no m1and m2 ..how to calculate its center of mass for ex: only m1 then how to finds its position "x" ..and its center of mass...?
The position of m1 is the distance from origin to m1. And the centre of mass of the particle is itself, i.e., mass of the particle itself.

thank you for that visual and your explanations sir! though I'm still trying to wrap my head around some of it. if I may, can I ask you a question. would I be right to assume that the center of mass on a human body is fixed and does not change no matter the position of the body, or does the center of mass change with the movement of body mechanics?
Thank you soooooooooo much for explaining so well .
Why is it that for two object of same mass, the curvature of spacetime is present where no mass is? What makes spacetime curve then?...
Are there any external force acting on geoid earth and its center of gravity changing in space ¿
great video!!!
Really well explained
Thanks
Helpful!
excellent
Thank you 😊
Hello, you say that there isn't external force, but I guess that you supposed to say: there is an external force, but it doesn't change the position of the center of mass. Am I right?
Well explained !
very useful
got it.
Keep going..
Thanks
If we divide an object at its COM, will the 2 side have same mass or not ?
perfectly explained
What will happen to the center of mass when the rocket breaks off?
Will the individual piece have its own center of mass ?
Yes
how to solve this-Two bodies of 2 Kg & 4 Kg are moving with velocities 20 m/s and 10 m/s respectively towards each other under mutual gravitational attraction. Find the velocity of their centre of mass in m/s.
Please reply
Thanks a million :)))
6:17 "X" is The disTance From where to C.M??
If we apply a constant force to the object, it will move with a constant acceleration and NOT with a constant velocity (Newton's second law!). The videos are great, but what the teacher is saying is wrong.
you are very fast
In bed I bet😏
Amaizing 🥰🙃
For whole COM

why people hate us
You definitely saved my life Thank you
Saved me from failing my final.
you just saved my academic life!
Oh god damn, my screen is dusty, thanks.
@Patrick Canaan thanks I dont care
Yes, this was very helpful. Thank you!
Thank you!
Thank you, you have saved me in a late minute physics assignment!!! Really good explination
This is gold
My physics class is on a time crunch and couldn’t really cover this topic, but now I understand it! Thank you
Hii have u graduated noww
Excellent Explanation
amazinggg,!
Excelente. Muchas gracias profesor.
is not gravity an external force which exerts on rocket during movement?
Tyre = Wheel
This was extremely helpful🙏
Thank-you so much😄
Oh hell yea that was helpful
excellent lecture thnk yu so much
How do you find the center of mass when the bar connecting the objects DOES have a mass?
That's simple...if the rod has a mass too..treat it like a small box in the centre with mass as much as that of the mass of the rod...and then these three are connected by a massless rod.. :) you can ask me if you want any more help or clarification.
good video
The problem uses sector formula
very helpful
Awesome
Thank you sir!
Very nice
thanks!
How is it that NO EXTERNAL FORCE acts on the rocket? Isn't the Parabolic path (projectile) a direct result of the gravitational force acting on it? And the velocity does not remain constant throughout. Correct me if I'm wrong.
Conservation of momentum fails to hold if Center-of-Mass frame is transformed by Lorentz Transformation to another inertial reference frame.
vixra.org/abs/1802.0099
If velocities of both objects are transformed by Lorentz Transformation. Total momentum become totally different.
Why do you multiply mass times distance? I assume you’re dividing by the sum of the masses to find the average...?
Ok!! Finally!! The best video I watched on Centre of Mass!!
clear to the point thank you sir
Very very cool! I need to pick up more physics to add to my math skillset.
great video bro you made it very simple to understand
How the formula for coordinates of c of m works
thank you so........very interesting!!!
thx man, your way of teaching is so awesome
Great vid, thank you!
Nice video my dear looking
Very nice concept
Thanks sir...........
mathwise: the barycenter
Why is it that for two object of same mass, the curvature of spacetime is present where no mass is? What makes spacetime curve then?...
Im so tired of learning things i won't ever use in my life :( But anyways, good video!
