    While I'm relatively new to WGT (months), I cant neglect but to comment on the perceived error in physics on the Greens. 

    From what I see, the initial attack of the ball is not calculated starting at 0,but instead is already being acted upon by the force of the tilt of the green.  

    if I am on a green tilting to the left or right, hitting across the slope,   the initial hit on theball is already rolling significantly down the slope where my "aim point' I way off of where the ball actually travels.

    I wanted to see if theres a way to improve the initial attack vectors on the ball with relation to green slope so it' more 'accurate'.

    here's some reference materials:

    http://www.puttingzone.com/Science/cjp-putting.pdf

    Pg 6, fig 4.

    in particular,  if I aim 5 degrees to the right of the pin, when I strike the ball, its already being acted on to the point where  instead of attacking at 5 degrees, its attacking at a "downhill" direction.  (like 3 degrees)...     the ball should always leave the club headed towards the aimed direction before being acted on by angular forces.

    hoping this will improve greens play..

    This is a well-known anamoly. The first few feet of a putt are much more impacted by a break than the last few feet, in complete contrast to what happens in real life.

    It isn't going to change. Learn it, love it, live it.

    Himehabu:

    Hey U Habu,

    This paper have better been graded by a professor that knows nothing of the game of golf.

    I don't know if it was you compiling this agglomeration, of prevarications.

    You physics geeks give me a splitting atomic cranial mass.

    Any armature serious in the game, knows the conditions on greens change every 30 minutes, due to time of day, humidity, barometric pressures, types of grass, and the lay of the grass, and many more factors, that are never constant.

    The variables of a ball traveling across any type of grass, are going to be inhibited by more unpredictable external forces than you could perceive. Unless you play the game.

    To just say "I am going to use "X" as a constant", is out side the totality of what you are trying to ascertain. If the variables are changing throughout the day, there is no constant to start an equation, completion of one so lengthy is ludicrous to the 10th power squared.

    I could assign "a" the value of a cow, then right an equation where simplified, 2+2 = cow

    You need to do better than that, to baffle me with bullshyt.

    You pulled from quite a substantial base of criterion as well. I wonder how many actually golf?

    Just like I wonder how all of a sudden the question of the voids in between galaxies were unknown materials for many decades. Until someone assigned the darkness, a value of "DARK MATTER".

    Can't see it, can't collect any of it, can't prove it, except using it in a theoretical quantum Mechanics equation.

    Miraculously now some of their postulated theories, are making sense, to the physics community.

    I say dark matter is really > COW FLATULENCE from galactic planets with cow spices running the roost.

    Cow flatulence being the constant, driving expanding gas, causing the increase in speed of which they, (galaxies) are moving faster apart from each other. Until coming to close to a nova, or gamma ray burst, and becoming ignited gas. Resulting in Newtonian propulsion.

    I can prove this theory in an in pressurized aircraft flying over certain parts of India, where the inside of the craft begins to smell as though wire casings are burning. Upon landing to check for catastrophic failure, of some instruments, we open the door and windows, only to be blown back into the cabin by the literal smell of cow flatulence.

    Cow flatulence is a pretty good constant in India. By your name, I have a strange feeling you may know what I am talking about.

    E=M (cow) 2

    LMAO,

    Thanks Joe for a great autopsy of the OP's post.   I knew I smelled either male bovine solids, or methane gas mixed with various aldehydes and ketones that had been expelled from the intestinal tract of the same animals when I first read it. 

    Well done Sir,

    Jeff

    This game doesn't use physics engines.

    The physics -

     

     

    The WGT virtual reality -

    They got ^^^^^^^^^^^^ that bit right at least.

    Just trying to keep the "harmonic" galactic balance

     

    Query for all science buffs.

    What's wrong with this picture?

    The Sombrero galaxy should be on top of the cat (when viewed from Earth it's horizontal) with the other celestial bodies!  Additionally this makes the Galaxy live up to it's name!  Also, this is TopGolf so it's only natural that the cat would be wearing a top hat.

    I suppose the harmonica should be under the cat so Wgt can play its own tune better not to mention its the only non spherical item we see??  I'm tired.  Don't think I answered it correctly lol.

    Good answer. The "foot break" sends the ball off on the wrong line if you ignore it.

    "if I aim 5 degrees to the right of the pin, when I strike the ball, its already being acted on to the point where  instead of attacking at 5 degrees, its attacking at a "downhill" direction.  (like 3 degrees)"

    The OP's comments do explain why purposefully missing the ding into the break seems to give the ball a truer more realistic roll.
