Motivation could be broadly defined as "the forces acting on or within a person that cause the arousal, direction, and persistence of goal-directed, voluntary effort." If you accept this definition, then perhaps the elements to which you refer are arousal, direction, and persistence.
Arousal of motivation refers to the conditions that impel a person to do something - the reason for the action. When I am hungry enough, I become motivated to find myself something to eat; motivation often comes from a need to address a situation.
Direction of motivation would address the type of action taken in response to the motivation. I might respond to being hungry by going to the kitchen and cooking a meal. I could also respond by getting in the car and driving to a restaurant. I could call someplace and have food delivered to my home. I might go to the park and steal someone's picnic lunch. All these actions would serve to meet the basic need.
Persistence refers to how hard or how long I will keep working to meet the need. If I discover I have only a few groceries available in the kitchen, I might decide to skip that meal; I might figure out a meal with what I do have available; I might consult recipe sources for a new dish I could make with what I have on hand; I might go grocery shopping to obtain ingredients for a better meal - different levels of determination and effort devoted to addressing the situation.
