falling with air resistance

This applet is falling with air resistance
Created by prof Hwang Modified by Ahmed
Original project requesting for simulations for object falling with air resistance/board:26-100-

What will happen if there are many objects with the same density but different size, all fall from the same height.
The terminal velocity $v=\sqrt{mg/b}=\sqrt{\rho Vg/b}$ , so the terminal velocity is proportiobal to $\sqrt{V}$ where $V$ is the volume of the object.

The following simulation try to illustrate the size effect on terminal velocity.
The ratio of the mass for the object is 1:2:3:4:5:6:7:8:9
Because it is a 2D simulation, the radius is proportional to $\sqrt{m}$ .

You can try it with different gravity g , or drag constant (Drag force = bv2)
