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)

Embed a running copy of this simulation

• 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!
