Disc / Wheel Rolling down Inclined Plane (Mechanics Problem)

A Disc / Wheel / Cylinder is rolling down an Inclined plane (or Hill) without slipping. The angle of inclination is theta. Find its acceleration.

In this video I solve the above problem using Newton's Laws.

[preeti]

Thanku sir....plzz continue your series...it's conceptually superb

[sametkacar]

Thank you, it's too helpful for me ❤

[Mandar_N]

For bicycle's rear wheel we take frictional force in forward direction itself i.e. the direction in which cycle is translating, but here we are taking it in opposite direction...can u please explain it why?? Please!

[delpino]

this was amazing!! thank you so very much 🙏🏼

[anjananaik]

Thank you... Sir please upload MSc physics Quantum mechanics and classical mechanics paper

[gunjangaur]

sir, may you please give a full lecture series on tensors using book Mathematical methods for physicists by Arfken and Weber as soon as possible 🙏🙏

[ihalilo]

what about torque's direction, shouldn't be minus sing

[boyajalandharnaidu]

Plzz explain about gyroscope effect sir...

[muhammedgunes]

When would one use f=N*f_k instead of the one you used and why. Is it only for linear motion without rotation.

[vatsavjosuyla]

Can u tell you.. Frcition is in opposite direction to motion.. Cuz in rolling motion friction is in the direction of motion ri8..

[el_witcher]

Thanks, Sir
Do you have a MSc or a PhD in Physics?
It looks like.
Quite smart guy.

[amcattili]

Sir if the surface is smooth then which is responsible for rolling

[frankvalen]

How did you get mgsin theeta and mgcos theeta

[mit-masterofinternettechno]

Do you have sample if there is friction (slipping) ?

[mr.spagal]

Plz make vedios on classical Mechanics for Bs students
Plzzzz

[akashkumargupta]

sir i kindly request u please make a video on ' parity, baryon number, Lepton number, Isospin, Strangeness and charm, concept of quark model, color quantum number and gluons '.

Dear sir, with due respect, the logic of deciding the direction of friction seems faulty. By extending this logic to a cylinder rolling up the incline, the friction should act down the incline, whereas it actually still acts up the incline. In my humble opinion, this will create more conceptual problems for students than resolve it.
