This action potential is moving along the axon at 20 m/s in the positive direction.1.1 Sketch the shape of the action potential as a function of position at some arbitrary moment in time.1.2Label the features of your sketch (A, B, C, D, E).1.3 What is the approximate distance between points A and E on your sketch

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
