ehhm
1) the spehere is not on the ground
2) i have the gravitation force and buoyancy force.
i link multiple sheres togehter to make a object physical "swim"
hey i need a formula to calculate the new velocity and rotation speed if i apply a force to a sphere (velocity and rotation speed are vectors).
i have the position of the sphere and force and the x/y/z "speed" of the force and the mass of the sphere.
would be cool if someone can help me
oh and i need it for 3d
omg you speak german this is godlike :D (i speak german too)
do you have msn or icq?
and thanks again
first thanks for the fast reply
@Tomura: Go i'm a noob at this things but i try to make it as good as i can.
J is the Moment of inertia tensor for your sphere (a 3*3 matrix).
a 3x3 matrix?
/X 0 0
\
\0 0 Z/
because i only know the formula J=2/5*m*r^2 (for sphere)
oh and you mean x = dot or cross
some code would be also fine because i can understand it better :)

no that's the problem else there would be no rotation speed
plz fast answer :(
