A falling raindrop
Kinetic energy and potential energy are both applied when a body or object is falling.
In the centripetal movement, what happens with velocity is that it will remain constant, always pointing in its tangential direction of the trajectory.

Both vectors as the turn is performed will always be perpendicular to each other.
