Just wanted to say this video is still helping people in 2020 :)

hey man u explain better than many teachers. thank you for every thing

[kyokokirigiri]

Thank you. I really appreciate your time and dedication to this content. You helped me really understand physics calculations.

[alexandrashields]

I like your tie-dye shirt! Thanks for sharing some info!

[barcaedition]

Thanks have an exam tomorrow you are better than my teacher
Hope i pass
Massive thanks from france

[cookiesfromkay]

Thanks! We used this in our science class to learn more about Equilibrium.

[realbetis]

Thanks for not making physics boring like every other video 😊

How'd you keep the camera on the moving car?

Just keep making videos guys i bet you r gonna get to a million subscribers

Thankyou so much...I understood, it is crystal clear explanation 🔥... something I watched worthy today, thankyou bro

As a physics teacher, educated in engineering, I would ask that there be some additional synonyms at the end. "Static equilibrium" being a well understood term for the case of non-moving equilibrium, and "dynamic equilibrium" being another term for "translational equilibrium". Using your flip videos is great! However, either because I'm lazy or just don't like having to explain why my terms are different from yours, it would be nice to have them mentioned :>)

I'm still struggling with this - how can the car move if there is no resultant force? I understand that it is moving at constant velocity, but doesn't it have to have a force stronger than the frictional force to move? So I don't understand why the x force equals to zero... I hope you can help me with this concept...

Sir, l have misconception that according to newtons third law that every action and has an equal and opposite reaction so if a car is moving with a velocity of 5

I have a question about the example of a vehicle being at equilibrium at a constant speed. It seems to me that although the example is interesting, that there are so many real life variables involved that in reality it would be virtually impossible to achieve. For example to maintain speed on a grade would require greater force or the conditions of the road itself could change things entirely (ie...paved road or gravel road). I'm not trying to argue for the sake of the argument but am rather interested to know if I am looking at this correctly or if all of that is irrelevant.

"the force of friction backward", what force is that? Please explain.

[targetmbbs]

Really great explanation with interesting view and funny too.

[learningisecstatic]

Sir force applied by the engine rotates the wheels of the car. Then what exactly causes the the force toward the forward direction on the car. Also friction acts to the opposite direction of motion resisting the motion and on absence of the friction the wheels will keep rotating at a fixed place. These two facts seem contradictory to me. I feel friction is pushing the car forward. Sir clarify my misconception please. Hope like before you will make a quick reply. Sir learning is ecstatic but confusion is tormenting. Love you sir.

How can it be possible that net force acting on a moving car is zero?
