Hi, I think this applet is great and I want to use it for my high school physics class.

My goal is to have my students investigate the relationships involved in circular motion.

I want them to understand the relationship between the following
- the centripetal force as a function of mass (with velocity and radius remaining constant)
- the centripetal force as a function of velocity (with mass and radius remaining constant)
- the centripetal force as a function of radius (with velocity and mass remaining constant)

With the applet, I have successfully been able to accomplish the third, but I can not find a way to manipulate for the other two.

Is there a way that can be done?

Thank you,
Nicole
