Late break isn't an optical illusion it's physics. Three forces on a pitched ball; gravity, the force from the pitch the projecting it forward, and air. Gravity of coarse makes it go down. The air slows it down and is what moves it with different spins giving it different movement from air flow. Last the force behind the ball. As long as it is greater, it reduces the impact of the other two. Since its force production stops the moment the hand is removed. It's force dissipates and the other two forces impact the ball more.
Imagine a bowler. The ball doesn't curve the entire bowl. At first it travels strait until the force projecting it away from the bowler dissipates enough that the force of friction moves the ball. Same thing just differnt forces.
Same as a draw or fade in golf. Not to be confused with a slice or hook which can in fact be curving the entire time. As such in the case, of when I hit a golf ball lol.
