Evolutionary Theory
The answer is force because Force is needed to change the direction of a moving mass.
Current means the present time, or a body of water moving in a definite direction.

This is one definition of acceleration (including deceleration) - any change in the speed of motion of a moving object, or in the direction of its motion. Motion is a vector value with both speed and direction.
Force changes either the speed or the direction of motion, or both.
A transverse wave would cause the displacement to be perpendicular to the direction. They will also be moving at a constant speed.
acceleration in a direction that is not parallel to the direction you are moving

Strictly you should ask whether a force can change the direction a body is moving in. The answer is yes.

Maybe, maybe not. Forces don't happen because you're moving ... forces are what cause you to move. If there are no forces acting on you, then you keep moving whichever way you're moving, and your speed or direction don't change. If there are forces acting on you, then your speed and/or direction can change. If the force is in the same direction that you're already moving, you'll move faster (accelerate). If the force is in the direction opposite to the direction you're moving, then your speed will decrease. Does any of this sound surprising ???
The word currents have several meanings. It could mean a body of water or air moving in a definite direction, or a flow of electricity.
