Hopefully putting the formulas for generalised energy and energy might help:
L=T-V (kin-pot)
generalised energy: h= \sum\frac{\partial L}{\partial \dot{q}}\dot{q}-L where \dot{q} should be bold and is the time derivative vector for all generalised coordinates.
and energy: E=T+V

I'm doing lagrangian mechanics and trying to understand my notes, are these three statements correct:
1. If kinetic energy is quadratic then energy equals generalised energy.
2. Saying kinetic energy of a system is quadratic is the same as saying none of the position vectors in a system...
