Okay, so the grass is wet. You either irrigate it or, you know, rains, which you can't control per se. So what happens is you get water on the grass and that acts as a lubricating layer, right, between the turf and the ball. And the moisture, it actually significantly reduces the coefficient of friction. So when a soccer ball hits the wet grass, significantly less than the ball, we call again, translational kinetic energy, less of that is converted into rotational energy. And this is because it doesn't decelerate at what you would think of as the expected rate of deceleration that you associate with typically dry turf. So the ball retains much more a greater percentage of its initial form of velocity. So what ends up happening is that the ball doesn't technically accelerate. It just skids rapidly on the wet grass. And because of this, for your perception.
