No, it can't be said that work is performed in this case.

Answer 2

Answer:

So, an object's kinetic energy will only change if the force acting on the object changes the object's speed. This will only happen if there is a component of the force in the direction that the object moves. Therefore, a force will do work only if the force has a component in the direction that the object moves.
