Firstly, thanks a lot for the rapid responses!
So for my experiment where the incline slowly increases linearly, I should just record the angle at when the different types of blocks begin to slide?
For example, the ice block begins to slide at 5 degrees.
u_s = tan theta
u_s = tan 5
u_s = 0.087...
For a personal project, I am analysing the physics in the Source video game engine and comparing it with real life.
I have set up in the engine a platform which increases in inclination from 0 to around 70 degrees.
On this platform there are four, equally weighted cubes each with a...
