while t

while t < 1: ## Change how much time elapses as necessary. ## Decrease this number if animation runs too quickly. Increase it or comment out if animation runs too slowly. ## Compute the net force on the green particle ## Update the momentum of the green particle ## Position update of the green particle greenparticle . pos = greenparticle . pos + pgreen/mgreen*deltat ## Append trail to follow the green particle trail . append (pos=greenparticle . pos ) ## Increase time t + deltat
