part of golf course where grass is kept short
Golf course The putting green, or simply the green, is an area of very closely trimmed grass on relatively even, smooth ground surrounding the hole, allowing players to make precision strokes on it. To "putt" is to play a stroke on this surface, usually with the eponymous "putter" club, which has very low loft so that the ball rolls smoothly along the ground, and hopefully into the cup. The shape and topology of the green can vary almost without limit, but for practical purposes the green is usually flatter than other areas of the course, though gentle slopes and undulations can add extra challenge to players who must account for these variations in their putting line. The green typically does not include any fully enclosed hazards such as sand or water; however, these hazards can be – and often are – placed adjacent to the green, and depending on the shape of the green and surrounding hazards, and the location of the hole (which often changes from day to day to promote even wear of the turf of the green), there may not be a direct putting line from a point on the green to the cup.
Golf equipment A tee is an object (wooden or plastic) that is pushed into or placed on the ground to rest a ball on top of for an easier shot; however, this is only allowed for the first stroke (tee shot or drive) of each hole. Conventional golf tees are basically spikes with a small cup on the head to hold the ball, and are usually made of wood or plastic. Wooden tees are generally very inexpensive and quite disposable; a player may damage or break many of these during the course of a round. Plastic tees are generally more expensive but last longer. The length of tees varies according to the club intended to be used and by personal preference; longer tees (3-3.5") allow the player to position the ball higher off the ground while remaining stable when planted, and are generally used for modern deep-faced woods. They can be planted deeper for use with other clubs but then tend to break more often. Shorter tees (1.5-2.5") are suitable for irons and are more easily inserted and less easily broken than long tees. Other designs of tee exist; the "step tee" is milled or molded with a spool-shaped upper half, and so generally provides a consistent ball height from shot to shot. The "brush tee" uses a collection of stiff bristles instead of a cup to position the ball; the design is touted by its manufacturer as providing less interference to the ball or club at impact, for a straighter, longer flight.
