What is the term for a movement made to achieve a specific goal?

The correct term for a movement made to achieve a specific goal is indeed "motor task." This concept refers to a planned and purposeful sequence of movements that are executed to accomplish a defined objective, such as scoring in a game, performing a gymnastic routine, or executing a dance sequence. Each motor task requires not only physical movement but also cognitive elements such as decision-making and strategy to effectively reach the intended goal.

While "motor skill" relates to the specific abilities involved in performing those movements, it does not capture the goal-oriented aspect inherent in a motor task. "Physical activity" broadly encompasses any movement that involves physical exertion, but it lacks the targeted intention towards achieving a specific outcome. "Motor development," on the other hand, refers to the progress of acquiring those skills over time, particularly in early childhood, and does not directly pertain to the execution of movements aimed at specific goals. Thus, "motor task" best encapsulates the idea of performed movements aimed at achieving a particular end result.
