====== The Kinetic Energy Density of a Rope that Supports a Wave ======

===== Prompt =====

** "What would be an expression for the kinetic energy density of an oscillatory system i.e. wave on a rope?" **


===== Context =====

This [[strategy:smallwhiteboard:|SWBQ]] is used to open up a discussion about energy density of an oscillatory system. 




===== Wrap Up =====

Students can easily come up with the equation for the kinetic energy density after given the explanation that //Energy Density// $= \frac{energy}{length}$. Student were having trouble to come up with the equation for the potential energy density.
