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.

@riteshbhartiya6155
@riteshbhartiya6155 4 года назад
Friction is opposite to the direction of motion at surface(slipping). Imagine the situation without friction the ball will slide down, so friction opposes that slipping and rotates the ball. In horizontal level, for example when a tyre of car rotates, without friction car won't go forward. Tyre will rotate on place. If you zoom at the point of contact you will notice actual slipping is backwards so friction acts forward and the car goes forward. Hope it helps;)

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

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.

But the friction does work downward if it rolls up
