MOI is moment of inertia, and this is basically the Golf club heads resistance to twisting. It applies to woods and drivers. When you hit a golf ball, the weight of the golf ball causes the quickly open and close many times. The more resistant the club head is to twisting the straighter the clubface will stay and obviously the straighter the ball will go.
putt
In the simplest terms, striking is hitting the ball.
Putter
The little holder for a golf ball is called a tee - when you tee off, you start a golf game by hitting the ball off of the holder.
Waggle?
a birdie
Try and focus on staying down on the ball, almost imagine you are hitting the ball into the ground, this will compress it and help get the ball in the air.
Golf uses a wedge. A wedge is a type of golf club and golfers mainly use it for hitting the golf ball out of the bunker. (sand pit).
The golf ball didn't spark, but it is very possible that you did see a spark. This happens when tiny tiny stones and even pieces of sand come in contact with the bottom of the club when you are hitting the ball. This will only have happened on clubs made from titanium such as drivers and some fairway woods.
I'm not exactly sure but I think it can be cause if a rock the size of a basketball (a meteor) is falling through the atmosphere it burns up before hitting the ground so i think a golf ball will.
if the golf ball is hit into the air, the forces on the golf ball are pushing (when the golf ball is hit) and air resistance (when it is flying through the air). when the ball hits the ground and starts to roll, the only force acting on it is friction.
It is probably not a bad idea to play golf wearing bifocals but it might make it hard for you to focus on the ball. It could also cause you to have less balance when you are hitting the ball.
