In the above file, a force at the top of the wheel is acting towards, right, and the friction at the bottom towards left.
But shouldn't the frictional force at the bottom point towards right?
Homework Equations
NA
The Attempt at a Solution
Second question: if a ball is rolling up an inclined plane, does the friction points upwards?
as it is slowing down the angular velocity so that the ang. velocity could be equal to the linear velocity that is being
slowed down by the gravity.
NA
