There's a statement I discovered in the book I am reading which says

Kinetic energy changes only when speed changes and that happens when the restaurantresultant force has a tangential component.

Does that mean Kinetickinetic energy will changechanges only when there is a resultant force component that is parallel to the velocity component? Or is something lacking in my understanding of the word tangential?

What is the tangential component of any vector?
