Hi Jack,

I have read your position on rotation and translation not occuring simultaneously.

However, I will offer proof to the contrary. Jack, take a baseball, and toss it to a partner at a short distance, throwing the ball as straight as possible. After a few tosses, asks your partner whether or not the ball spins.

When performed, you will discover that the ball travels in a line, or possesses a linear component to it. Yet, the ball also spins, or displays a propensity to gyrate. Moreover, the ball travels in a line and spins simultaneously, showing that linear and rotational activity can be concomitant.

On these grounds, I reject your premise that linear and rotational movement cannot occur at the same time.

Best,
BHL
