    Hey guys, why don't you get on the thread I started on shot quality and shoot me down (with friendly fire, mind you)! The two things I mention there made a huge difference to me. If you can add your insight, it'll be great. Physics is welcome, although it's been many years since I've had to solve a differential equation involving mass, time, and distance... :)

    in your earlier posts , u said you are a 4.0-4.5

    and never played a tournament.

    why dont u post a video how you hit your forehand?

    come forward or you will end up like boredo. cant hit a winner for his life.

    Pushing_wins,

    I've been on this forum for 2 years. I've been playing tennis for 2.5 years. I'm sure there was a time I was posting on this forum that I hadn't played a tournament and would have described myself as 4.0-4.5. I'll post a video of my forehand at some point soon if you really want.

    Yes, good discussion. Whatever was worthless to you was worth something to me and vice versa. We just simply disagreed as to how an open stance forehand should be hit. I dont disagree with you, but I also am not going to limit my understanding of the stroke to just angular momentum. If you want to, that is fine with me.

    I just think there is more happening in a tennis stroke besides angular momentum in its strictest sense and if I was looking at a player from above down towards his head, I envision something like what is shown below. However, I can also see it going back and described as you have said - up.

    Anyway, I am out of here Good luck.

    Of course you must be able to time it to hit a ball effectively. It's one of the big reasons that some people swing harder, but get less mph.

    I don't suppose it would help for me to reference the physics phd who is also a tennis certified instructor who shared with me about the formula for Momentum and how distance is not part of the equation? Remember, I didn't say YOU could use a 1/4 inch, I said the formula only accounts for speed, not distance. So there is no insignificant distance, only insignificant speed.

    If you move 1/4 of an inch forward during the motion, the velocity of your movement will be much less than if you move a foot during the motion.

    Quote above is absolutely incorrect and not based on anything but an armchair opinion.

    In the context of an airbourne sit & lift forehand + all else equal, it is indeed accurate.

    Unrealistic doesn't mean impossible. It simply means it's unrealistic in this context.

    P = mv (Linear momentum/P = measurement of the tendency of an object moving in a direction to continue moving at the same speed in the same direction.)

    Mass is constant, so in the context of an airbourne sit/lift forehand: The greater the velocity of your forward movement, the greater the momentum and therefore the greater the distance of travel.

    --

    Do you think you can add a few inches and only a few inches of forward CM movement to a forehand, at a speed that would make it worth the addition?
