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.

@emlmm88 8 лет назад

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.

@archetypex65 7 лет назад

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?

@kayfincher374 6 лет назад

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...

@albertzheng182 3 года назад

6:17 "X" is The disTance From where to C.M??

@themasteryocheese8133 3 года назад

Oh hell yea that was helpful

@abhashrivastava8492 6 лет назад

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.

@sreekayal1428 6 лет назад

If we divide an object at its COM, will the 2 side have same mass or not ?

@arunasaikia8999 5 лет назад

@virsuryaircas 8 лет назад

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...?

@gsisirvarma6160 8 лет назад

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.

How the formula for coordinates of c of m works

@saramorimoto2945 8 лет назад

How do you find the center of mass when the bar connecting the objects DOES have a mass?

@arpandutta3591 8 лет назад

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.

@renesoucy3444 Год назад

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?...

@enzoylautixD 6 лет назад

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?

@andrewhuffaker5512 6 лет назад

Why do you multiply mass times distance? I assume you’re dividing by the sum of the masses to find the average...?

@adidebdas2703 6 лет назад

What will happen to the center of mass when the rocket breaks off? Will the individual piece have its own center of mass ?

@kotaiahpatti5688 6 лет назад

Yes

@plsacceptthisone 2 года назад

is not gravity an external force which exerts on rocket during movement?

@heroicgamersingh4963 6 лет назад

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.

@heroicgamersingh4963 6 лет назад

Please reply

@ericsu4667 6 лет назад

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.

@ivelinabobtcheva9177 4 года назад

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.
