Moving camera, but good video. Doc Schuster Inclined Plane and Box Sliding on a Ramp with No Acceleration
Interactive physics problem set/quiz; Normal Forces
Not a fan of the notation but the rest seem OK, still like the video above and Andrew's problems more though; ScienceNotes Friction Inclined Plane
Example 1: playing with a sled.
Example 2: now with more friction!
Example 3: Intigrated problem.
An Atwood inclined plane problem step by step problem solving with connection between FBD and 2nd law.
A quick worked problem 3 min
Some good practice problems You do have to pay for the soltuions which ain't cool.
More problems but no solutions.
