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)

  • Please feel free to post your ideas about how to use the simulation for better teaching and learning.
  • Post questions to be asked to help students to think, to explore.
  • Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!
