    Determination of coefficient of friction between two spherical particles

    I have some very small spherical particles with diameter of 1 mm and i would like to know coefficient of friction between them. Can anyone suggest an experiment/device that would help me? In order to get friction between a plate and particle i can use tilt test and measure the angle at which...

    Finding Force Field Parameters for Molecular Modeling | Sigma & Epsilon

    Ok i found that AMBER force field parameters are avalible on their homepage: http://amber.scripps.edu/ and there is also a link to some other page where they have a nice file: http://www.chpc.utah.edu/~cheatham/cornell_all_prm But anyway i would like more LJ parameters if you have.. see PM please.

    Finding Force Field Parameters for Molecular Modeling | Sigma & Epsilon

    Thank you for your links! The last one looks the most interesting to me. I am interested in organic compound.. so mainly C H O N P S elements. I can't access the article on wiley page though.

    Finding Force Field Parameters for Molecular Modeling | Sigma & Epsilon

    I am looking for some force field parameters for nonbonded forces between atoms. In most molecular modeling programs Lennard-Jones function is used to calculate Van der Waals forces where sigma and epsilon are constant values for a pair of atoms. But i cannot find them anywhere. Or if...

    Basic motion stuffs, time and velociton

    s_a = s_b s_a = s_0 + v_a * t s_b = v_b * t Insert both in first equation and calculate t.
