Generalised energy and energy (lagrangian mechanics)?

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 depend explicitly on time.

3. A lagrangian can be independent of time (generalised energy is conserved) even if kinetic energy is not quadratic (energy DOESN'T equal generalised energy)

Can a Mod delete this, no answer and I worked it out.

We don't generally delete threads. I have marked it as "Solved", however.
