For the stop watch shown in the attached file (picture):
Outer dial is divided into 60 seconds with 1,5 second graduations.
Smaller circle do one hour for each revolution.

I do not unstand your picture. Why the divisions are 100 and 30?
Please explaine it in more detail.
I need more information to create a stop watch you need!

You can check out similar applet at A real time clock created with EJS4

I just created a stop watch simulation similar to the above picture (But not exactly the same).
Let me know if this is what you want. (You did not specify the functions you need!)

Embed a running copy of this simulation

Embed a running copy link(show simulation in a popuped window)
Full screen applet or Problem viewing java?Add http://www.phy.ntnu.edu.tw/ to exception site list
Press the Alt key and the left mouse button to drag the applet off the browser and onto the desktop. This work is licensed under a Creative Commons Attribution 2.5 Taiwan License
  • 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!
