Thanks for replying, it makes sense that kinetic energy is only a function of time physically, however by looking the equation above since y=y(x,t), shouldn't ∂y/∂t be also a function of both position and time?

Homework Statement In our physics course, we were studying one dimensional waves in a string. There, our teacher stated that the kinetic energy in a small piece of a string is dK=\frac{1}{2}μdx\frac{\partial y}{\partial t}^2 were μ is the linear density of the string, so he claimed that...
