Kinetic energy is defined by an object's motion. Time is not a factor. Here's another way of looking at your question...you make a cake, comprised of sugar, flour, eggs, milk and whatever else...the discreet ingredients are lost in the mix and are indistinguishable when the cake comes out of the oven...mass and velocity determine kinetic energy...time as a discreet ingredient of velocity and gets lost in the result.
Unit definitions are also at play here...in physics class, when you determine kinetic energy, the answer you end up with will most likely be in joules...here's a conversion table.

A foot-pound is 1.356 joules. When you calculate in one system and convert to another, each discreet element gets lost.
