Static and Dynamic Equilibrium

[AKLECTURES]

Thanks for commenting. Let me clear up an important point about dynamic equilibrium. In dynamic equilibrium, an object is either traveling with some constant translational velocity or a constant angular velocity. It is NOT, as you put it, accelerating. Therefore, according to Newton's Second Law of Motion, the object has a net force of zero along any direction in three dimensional plane. For instance, a box traveling across a frictional surface at a cosntant velocity is not accelerating and

therefore is in dynamic equilibrium (it is still traveling with some velocity).

thanks for uploading this video. I would like to give my comments on it. general speaking we have two types of equilibrium: static and dynamic. in static as you mentioned the net force is zero while the system can have the zero velocity or constant velocity but for the second case the object accelerated due to out-of-ballance force. It means for the dynamic equilibrium the object is accelerated. So we dont have the third type.

Thank you for posting this video. It was extremely helpful. Great Job. Appreciative of how you thoroughly explain everything and give examples. Too bad some teachers can't find this balance you have of being very clear, direct and informative in a small amount of time. THANKS AGAIN!

Thanks a lot for a great explanation of equilibrium concept! Appreciate it!

Thank you so much. I'm very confused about this topic.
now, I'm doing statics homework.

Perfect, how didn't your channel got at least one millon subs till now.

Thank you for the video. The explanation is so clear .

[MrALOK-twho]

Thanks for proper information and doubt clearance...

Yea this is not correct. Rotating objects are constantly accelerating. They have a “centripetal acceleration”. Their speed may be constant, but their velocity is not. Maybe you meant to say that their angular acceleration is zero?

Quality content!
Thank you for clearing things up !!! 💖

[mafelgubatan]

you kind of look like sheldon (from the big bang theory) from the back haha. anyways, thanks for the video. very helpful :)

I would like to point out a mistake in your definition of dynamic equilibrium. Newton's first law allows motion but only in a straight line. Therefore, dynamic equilibrium allows for motion along an axis (translational velocity), but NOT motion "about" an axis (rotational velocity). Having a non -zero rotational velocity means that an object is continuously changing direction or, in other words, the object is accelerating. Whether or not the magnitude of angular velocity is constant doesn't matter, the object is still accelerating and therefore not in dynamic equilibrium.

Thank you this video is very very helpful

Very clear.u explained it so nicely 😘😘thank u 😄 Soo much .

[nouramohamed]

Thank you so much this was very helpful

[bilalzafar]

Sir it's ver y helpful thanks alot

[hussainalali]

Thank you for you useful videos, can you explain Si units and prefix to me, please?

[bhoopendramishra]

What will happen when body is moving constant acceleration ?
Then it ll be the dynamic equallibrium or not?

[akrititrehan]

can you give an example of "not in equilibrium"
