A mass m attached to a vertical spring (spring constant k) in gravity field:
The above system can be described with
F=m a_y= mg -ky -b v_y or m\frac{d^2y}{dt^2}+b\frac{dy}{dt}+ky=mg

For a RLC circuit with DC source Vc:
The above system can be described with
Vc=V_L+V_R+V_C or L \frac{d^2Q}{dt^2}+I\frac{dQ}{dt}+\frac{Q}{C}=Vc,
 where I=\frac{dQ}{dt}, V_R=I R, V_C=Q/C , V_L=L\frac{dI}{dt}

The differential equation are the same for the above two systems.
So a damped spring system can be simulated with RLC circuit (or RLC circuit can be simulated with damped spring system,too!).

  • 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!
