Hey Ken are you enjoying this? I put a lot of work into this one. And Tom yeah I'm listening. Keep going. Okay Ken's big into physics. VA 3VWX. So here's another question. Does wet grass slow the ball down or does it speed it up? Alright this is a really interesting one. So we spoke about the the atmosphere and temperature and air density and all that stuff and the effects it has. But from a physics standpoint no surface can impart forward acceleration to an unpowered object right that's the general rule. So the ball can't travel faster than the initial velocity imparted by you know a player's boot. When you kick the ball it's going to go with that velocity. But what ends up happening is that the perception of the ball speeding up on wet grass. This is a sort of grounded end.
