Newton`s Second Law of Motion
... Only motion in a straight line is motion that is not changing its direction. Movement in a circle is actually a continuous changing of directions. Therefore, it must be undergoing an acceleration. Ask what force is acting on the yo-yo to change its direction. In an open discussion, explain to stude ...
