velocity_verlet_propagator_1()

void velocity_verlet_propagator_1 ( Particle &  p, double  time_step  )

inline

Propagate the velocities and positions.

Integration steps before force calculation of the Velocity Verlet integrator:

\[ v(t+0.5 \Delta t) = v(t) + 0.5 \Delta t f(t)/m \]

\[ p(t+\Delta t) = p(t) + \Delta t v(t+0.5 \Delta t) \]
