If an object is traveling in a circle we could describe its motion with the usual variables for position, velocity, and acceleration, but it would be complicated because the objects direction is constantly changing. It is more convenient to define new variables to describe circular motion in angular units.
Ernie Els Makes The Switch Back To A Regular Sized Putter. Four-time major champion, Ernie Els is using the European Tourâs Desert Swing to work out some equipment changes. The popular 44 year-old from Johannesburg, South Africa switched from Callaway to Adams during the off-season, and has decided to get ahead of the putter ruling, and back to a normal length putter.
Ernie demonstrated incredible resolve to not only keep playing, but to play the remaining 17 holes in just three over, on a day when even players who weren't six-putting were struggling to shoot good scores. I can't explain it. I couldn't take the putter back, said Els. I had three goes and then it went all over the place. Something withholds you from doing your normal thing. Els, who suffered with the yips several times last year, seemed to be finding it impossible to deal with his demons.
