A racket, or racquet, is a sports implement used for striking a ball or shuttlecock in games such as squash, tennis, racquetball, badminton and padel. In the strictest sense a racket consists of a handled frame with an open hoop across which a network of strings is stretched tightly. Some rackets may have a solid or perforated hitting surface instead of a network of strings. Such rackets may be called a paddle or bat. Collectively, these games are known as racket sports.
Softball is a game similar to baseball played with a larger ball on a smaller field, with only underhand pitches permitted. Softball is played competitively at club levels, the college level, and the professional level. The game was first created in 1887 in Chicago by George Hancock.
A cricket bat is a specialised piece of equipment used by batters in the sport of cricket to hit the ball, typically consisting of a cane handle attached to a flat-fronted willow-wood blade. It may also be used by a batter who is making batter's ground to avoid a run out, by holding the bat and touching the ground with it. The length of the bat may be no more than 38 inches and the width no more than 4.25 inches. Its use is first mentioned in 1624. Since 1979, a law change has provided that cricket bats can only be made from wood.

The organization is responsible for the continued proliferation and health of the sport, and leads a number of amateur initiatives through its Sport Development department, including Play Ball and Pitch Smart. USA Baseball also presents the Golden Spikes Award annually to the top amateur baseball player in the country and is responsible for creating the USABat standard.
A baseball bat is a smooth wooden or metal club used in the sport of baseball to hit the ball after it is thrown by the pitcher. By regulation it may be no more than 2.75 inches (7.0 cm) in diameter at the thickest part and no more than 42 inches (1.067 m) in length. Although historically bats approaching 3 pounds (1.4 kg) were swung, today bats of 33 ounces (0.94 kg) are common, topping out at 34 to 36 ounces.
In baseball, batting is the act of facing the opposing pitcher and trying to produce offense for one's team. A batter or hitter is a person whose turn it is to face the pitcher. The three main goals of batters are to become a baserunner, to drive runners home or to advance runners along the bases for others to drive home, but the techniques and strategies they use to do so vary. Hitting uses a motion that is virtually unique to baseball and its fellow bat-and-ball sports, one that is rarely used in other sports. Hitting is unique because it involves rotating in the horizontal plane of movement, unlike most sports movements which occur in the vertical plane.

College baseball is baseball that is played on the intercollegiate level at institutions of higher education. In comparison to football and basketball, college competition in the United States plays a smaller role in developing professional players, as baseball's professional minor leagues are more extensive, with a greater history of supplying players to Major League Baseball (MLB). Moving directly from high school to the professional level is more common in baseball than in football or basketball. However, if players opt to enroll at a four-year college, they must complete three years of college to regain professional eligibility, or have turned at least age 21 before starting their third year of college. Players who enroll at junior colleges regain eligibility after one year at that level. During the ongoing regular season, 301 teams have competed in NCAA Division I in the United States, with top teams progressing through the regular season, various conference tournaments and championship series, and the 2023 NCAA Division I baseball tournament to play for the Division I championship in the 2023 Men's College World Series.
Collegiate summer baseball leagues are amateur baseball leagues in the United States and Canada featuring players who have attended at least one year of college and have at least one year of athletic eligibility remaining. Generally, they operate from early June to early August. In contrast to college baseball, which allow aluminum or other composite baseball bats, players in these leagues use only wooden bats, hence the common nickname of these leagues as "wood-bat leagues". Collegiate summer leagues allow college baseball players the ability to compete using professional rules and equipment, giving them experience and allowing professional scouts the opportunity to observe players under such conditions.
In mechanics, an impact is when two bodies collide. During this collision, both bodies decelerate. The deceleration causes a high force or shock, applied over a short time period. A high force, over a short duration, usually causes more damage to both bodies than a lower force applied over a proportionally longer duration.

A basketball is a spherical ball used in basketball games. Basketballs usually range in size from very small promotional items that are only a few inches in diameter to extra large balls nearly 2 feet (60 cm) in diameter used in training exercises. For example, a youth basketball could be 27 inches (69 cm) in circumference, while a National Collegiate Athletic Association (NCAA) men's ball would be a maximum of 30 inches (76 cm) and an NCAA women's ball would be a maximum of 29 inches (74 cm). The standard for a basketball in the National Basketball Association (NBA) is 29.5 inches (75 cm) in circumference and for the Women's National Basketball Association (WNBA), a maximum circumference of 29 inches (74 cm). High school and junior leagues normally use NCAA, NBA or WNBA sized balls.

Composite baseball bats, opposed to aluminum or wood baseball bats, incorporate a reinforced carbon fiber polymer, or composite, into the bat's construction. This composite material can make up all or part of the bat. Bats made entirely of this polymer are referred to as composite bats. Bats which only incorporate a portion of polymer are referred to as composite hybr Composite bats can also be constructed to improve their trampoline effect over time. That advantage, namely the improved trampoline effect over a break in period, put the use of composite bats under further NCAA scrutiny during the 2009 NCAA Division I baseball tournament. Composite bats, tested after they were already broke in, showed performance standards well beyond the accepted ball exit speed ratio (BESR) Test.

NOCSAE conducts and funds scientific research and collects and analyzes data relating to standards development.
Boning is the practice in American baseball of treating a baseball bat with a bone. The bone is run repeatedly up and down the barrel of the bat. The practice has the benefit of slightly hardening the bat by compressing the surface wood cells, and also of boosting hitting on the grounds that bone and hide go together, thus bone attracts hide, and as the baseball is covered in hide it will be attracted to the boned bat.
