It is true that the potential must be strong enough to send
a potential to the CNS. The stronger the potential, the more it will excite the
transmitter in relaying the message to another neuron, therefore, if this
happens, the more will it be easier to pass the message.
At the very top of the swing the velocity=0. If the velocity is 0 then the kinetic energy is 0 as well because kinetic energy is the energy of movement.
