it's a scalar quantity.
because Note that besides kinetic energy, we have another motion-related quantity which is a vector, namely momentum. Just as an object's kinetic energy changes because of the net work done on it, so does the object's momentum change because of the net impulse acting on it (force x time in the simplest case). And impulse is a vector, like momentum is.
