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 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.
