The equilibrium position can be varied in this simulation.
The spring will try to move back to it's equilibrium position.
The differential equations are:
\( \frac{dx}{dt} = v \)
\( \frac{dv}{dt} = a = \frac{k x}{m} - \frac{\mu g }{m} \)
here is a friction force between block and the floor, Fr= -mu*m*g;
