CM Yep, it is. A big boulder sitting on top of a high cliff
CM contains a lot of potential energy. Voltage is literally
CM potential energy and cannot exist without energy.


If I can manage to roll the boulder up at the top or at the bottom of
the cliff, I will find it weighs about the same. The boulder only
picks up energy as it is accelerating towards the foot of the cliff.

W R O N G !!!!!!!!!!!!!!!!!!!!!

The boulder has energy simply because it is on top of the cliff.
[Potential Energy].

As it accelerates towards the bottom of the cliff the energy changes [
CHANGES ] from POTENTIAL to KINETIC.

The 11th commandment: Energy can be neither created nor destroyed: just
changed in type of energy.

A*s*i*m*o*v, you need to refresh your freshman University Physicss.
