The energy that the object has when it's spinning is never "used up", unless
there's something acting on the object to rob energy from it. In our daily
experience on Earth, there's ALWAYS some friction acting on a spinning object.
The friction robs energy from it, and it eventually stops spinning. That's why
it's so hard for us to understand and accept Newton's law that tells us how
things REALLY work. An object in motion continues in motion unless it's acted
on by an external force. In other words, if something is moving, it doesn't take
any force or action to KEEP it moving. We just never see this happen on Earth,
because we can never set anything up WITHOUT any outside forces that act
to make it stop, so we always have to do something to keep it moving.
A perpetual motion machine is something that will keep spinning or moving (typically involves rotation, but not always) forever without the need to keep adding energy. These are typically viewed as something that will move forever that we can connect a generator to in order to obtain free infinate energy.
It tends to lose rotational energy due to friction.
Inertia is the energy contained in an objects motion. Its' potential to do work. A spinning top has inertia as does the World or any planet. This spinning motion can be made to do work and slows as it gives up its' energy. Mass plus spin or gravity generate power.
That is not a very accurate description. Kinetic energy is the energy of motion, or the energy that something has because of its motion.
The spinning top has uniform motion.
A spinning top is a moving mass, and this represents a form of mechanical energy we call kinetic energy, which is the energy of motion.

The force of friction will eventually steal away the energy of the spinning top, and it will fall over.
