Hey everyone! So I'm looking at the energy transfers in a mass-spring system oscillating with simple harmonic motion, and I'm a bit confused.
So, for the graph of total energy, potential energy and kinetic energy against displacement:
I think it suggests that when the kinetic energy of the system is at a maximum value, the potential energy is 0.
But, for vertical (and horizontal? not sure) mass-spring systems, when the kinetic energy is maximum as the mass passes through the equilibrium position, the potential energy isn't 0, correct? Since, at that instant there is a non-0 value for extension, no?
Which bit of my thinking is wrong? Or does the graph only apply to simple pendulums ?
Cheers
