At risk of digression, my understanding is that light is not visible insofar as it is energy, but rather it is by its interaction with certain particles that we perceive it. Take for instance, the photon, which, if I am not mistaken, is not technically energy. In a similar sense, kinetic energy is perceptible in the sense that a moving object is perceptible, but in a more abstract sense, inherently invisble.
