For a personal project, I am analysing the physics in the Source video game engine and comparing it with real life.(adsbygoogle = window.adsbygoogle || []).push({});

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 different material property: slime, ice, wood, and rubber. The weights of the cubes are modifiable and the angle of the platform is measurable.

I have been told to use the coefficient of static friction equation. This is listed in "Physics" by Jim Breithaupt (1999, Macmillan Press, ISBN: 0333733028) as:

μ = W sin theta / W cos theta

Is this correct and relevant to my needs? Does this take into consideration the material properties of the blocks? How can I use the results in a meaningful manner?

Additional:

I have been told that this experiment can be used with the equations:

sin theta * gravity * mass = pulling along force

cos theta * gravity * mass = pulling down onto surface force

Any explanation into this would be greatly appreciated,

Kind regards,

Danilo Vujevic.
