Around 56g-58g.\n\nA tennis ball is hollow and composed of inflated rubber, covered with a fabric which must be uniform. Its between 2 1/2 and 2 5/8 inches (6.35 and 6.67 cm) in diameter and weighs between 2 and 2 1/16 ounces (57.7 and 58.5 grams). Yellow and white balls are used in competition. When dropped on concrete from a height of 100 inches (2.5 meters), they must bounce upward from 53 to 56 inches (135 to 147 centimeters). The serve is the most important stroke in tennis.\n\nLitell, Mifflin. Integrated Mathematics. Evanston, IL: 1995.

Well nowadays there's really only two major types of balls. Multilayer balls and one piece balls. \n\nOne piece is your basic Top-Flite XL or Pinnacle Gold....just meant for distance only and you can buy a dozen at your local Wal-Mart for 10 bucks. \n\nMultilayer balls are more expensive and meant for the player seeking different levels of performance in his/her game. Relating to their construction they're meant to have differing levels of spin and launch angles depending on what type of player is playing them. \n\nThe Titleist Pro V series is a good example of a ball for good players. It spins hard off the wedges and launches high with very little spin (relative to other high spin balls) off the driver. \n\nThe Maxfli Noodle would be an example of a ball that doesn't have a lot of spin off the driver either, but it doesn't spin as hard off the wedge.....but it would be cheaper than the Pro V....\n\nSo when choosing a ball it all depends upon what type of player you are and what type of performance you want out of your golf ball.

Golf is a sport about patience and skill. Its not boring to watch if you know how to appreciate the game!

A softball is made of cork, yarn, leather, and basically the same material as a baseball. The inside is held together with compressed air. The higher the core of the compressed air, the further the ball goes and the harder it is.

Aerodynamics\n\nWhen a golf ball is hit, the impact, which lasts less than a millisecond, determines the ball’s velocity, launch angle and spin rate, all of which influence its trajectory (and its behavior when it hits the ground).\n\nA ball moving through air experiences two major forces: lift and drag. Drag slows the forward motion, whereas lift acts in a direction perpendicular to it. The magnitude of these forces depends on the behavior of the boundary layer of air moving with the ball surface.\n\nEvery modern golf ball has dimples; their purpose is to increase and shape the lift and drag forces by modifying the behavior of the boundary layer. It should be noted that drag and lift forces exist also on smooth balls: they are only modified, not created, by dimples.\n\nOne effect of dimples is a reduction of drag, contributing to the increased length of flight of dimpled balls compared with smooth ones.\n\nA spinning ball deforms the flow of air around it, thus acting similar to an airplane wing. Backspin is imparted in almost every shot due to the golf club's loft (i.e. angle between the clubface and a vertical plane). A backspinning ball experiences an upward lift force which makes it fly higher and longer than a ball without spin would. Sidespin occurs when the clubface is not aligned perpendicularly to the direction of swing, leading to a lift force that makes the ball curve to a side. These lift forces are further increased through the presence of dimples.\n\nIn order to keep the aerodynamics optimal, the ball needs to be clean. Golfers can wash their golf balls manually, but there are also mechanical ball washers available.\n[edit]\n\nDesign\nA two-piece golf ball with large and small dimples\nEnlarge\nA two-piece golf ball with large and small dimples\n\nMost balls on sale today have about 300 to 450 dimples. There were a few balls having over 500 dimples before. The record holder was a ball with 1,070 dimples -- 414 larger ones (in four different sizes) and 656 pinhead-sized ones. All brands of balls, except one, have even-numbered dimples. The only odd-numbered ball on market is a ball with 333 dimples.\n\nOfficially sanctioned balls are designed to be as symmetrical as possible. This symmetry is the result of a dispute that stemmed from the Polara, a ball sold in the late 1970s that had six rows of normal dimples on its equator but very shallow dimples elsewhere. This asymmetrical design helped the ball self-adjust its spin-axis during the flight. The USGA refused to sanction it for tournament play and, in 1981, changed the rules to ban aerodynamic asymmetrical balls. Polara's producer sued the USGA and the association paid US$1.375 million in a 1985 out-of-court settlement.\n\nThe United States Patent and Trademark Office's patent database is a good source of past dimple designs. Most designs are based on Platonic solids such as icosahedron.

It is about the laws of motion and the physics of a collision.  The collision here is the the golf iron colliding with the golf ball - the iron of course transfering enough energy to the golf ball to send it winging through the air. It is also about efficiency.  The heavy mass at the end of long thin pole allows a faster swing, thus increasing the opportunity to impart momentum to the golf ball.  Newton's three laws explain all this. See below.\n\nFor the second piece of effiency one must understand elastic collisions transfer energy better than inelastic collisions.  To make the collision between iron and ball more elastic, the ball is built with a spongy center and flexible shell.  Thus when the iron hits the ball it momentary deforms so as to mimic an elastic collision and thus capture more of the iron's energy.

Again, it depende son the ball and the brand. Most balls have between 300 and 450. All but one brand of ball has an even number of dimples, the odd one being 333. The most dimples ever put on a golf ball was 1070. It had 414 larger dimples and the rest were pin head sized holes.

Cricket balls are made from a core of cork, which is layered with tightly wound string, and covered by a leather case with a slightly raised sewn seam. The covering is constructed of four pieces of leather shaped similar to the peel of a quartered orange, but one hemisphere is rotated by 90 degrees with respect to the other. The "equator" of the ball is stitched with string to form the seam, with a total of six rows of stitches. The remaining two joins between the leather pieces are left unstitched.\n\nFor men's cricket, the ball must weigh between 5.5 and 5.75 ounces (155.9 and 163.0 g) and measure between 8 13/16 and 9 in (224 and 229 mm) in circumference. Balls used in women's and youth matches are slightly smaller.\n\nCricket balls are traditionally dyed red, and red balls are used in Test cricket and First-class cricket. White balls were introduced when one-day matches began being played at night under floodlights, as they are more visible at night. Many one-day matches are now played with white balls. Other colours have occasionally been experimented with, such as yellow and orange for improved night visibility, but the colouring process has so far rendered such balls unsuitable for professional play because they wear differently to standard balls.The white ball has been found to swing a lot more during the first half of the innings than the red ball.It also deteriorates faster than the red ball.
