The energy needed to cause an action potential in a neuron is about 70-75 millivolts. This voltage change is generated by ion movements across the neuron's cell membrane, specifically involving sodium and potassium ions.
Potential energy is energy that is currently stored in an object but has the potential to cause changes in the future. This energy is not actively causing changes at the moment, but it can be released to do work or create movement. Examples of potential energy include gravitational potential energy, elastic potential energy, and chemical potential energy.
Potential energy increases when an object is raised to a higher position against the force of gravity, when an object is compressed or stretched (elastic potential energy), or when electric charges are separated (electric potential energy).
When energy is wound up, it is typically stored in the form of potential energy, such as elastic potential energy in a wound-up spring or gravitational potential energy in an elevated object. This stored energy can be released later to do work or cause motion.
A cause of mechanical energy is the motion of an object due to its position or movement. This energy can be transformed between potential energy (stored energy based on position) and kinetic energy (energy of motion).
You can increase the elastic potential energy of a rubber band by stretching it further from its natural length. This will cause the rubber band to store more potential energy as elastic potential energy increases with the amount of stretch applied.
thermal energy is needed to do that job. as opposed to mechanical potential or chemical energies.

potential energy
Potential energy is stored energy capable of doing work. Since energy is general comes from the food we eat, so does potential energy.
A synapse and an action potential have a flip-flopping cause and effect relationship, in that an action potential in a presynaptic neuron initiates a release of neurotransmitters across a synapse, which can then subsequently potentially trigger an action potential in the axon of the postsynaptic neuron, which would then cause release of neurotransmitters across a following synapse.
No, subthreshold stimulation is not sufficient to trigger an action potential. The membrane potential needs to reach a certain threshold level for an action potential to be generated. Subthreshold stimulation only produces graded potentials that do not reach the threshold for firing an action potential.
