    • Enjoy the fun of physics with simulations
The following simulation show relations between displacement($x$), velocity($v_x$), acceleration ($a_x=-k*x/m$),force($F_x=-k*x$), kinetic energy($K=   frac{1}{2}m*v_x^2$) and potential energy($U(x)=   frac{1}{2}k*x^2$)

Drag the blue object at one end of the spring and let go.

Drag force is added. 2011/03/18 $F=-k*x-b*v_x$

nice applet above. :D
Like the speed controller on the right slider allow for speedy exploration by students
Like the Drag the blue object at one end of the spring and let go, clear instruction on what the applet can do.

just to share i also have one similar

customized to my style and teaching needs

btw some guy (founder of PhyzixLabs Software ( introduce this to me

I like, different design with a good idea about SHM, nice work prof.
