some of useful features include
for an expanded view or close up view of the F-t graph, move the carts by dragging on the carts near to the right side of the world view, as the plot detects the Tmax for simulation to run.

mr yip old version of my model does not really simulate the Force-time graph at collision as i used a cheating method to trick the dt to be sizeable for a detectable F-t graph but the problem is when the collision is ideal, the dt is actually zero as the computational method brings the 2 masses together at precisely the exact time, making dt =0 for calculation of Force infinity.
