Hockey is a fast-paced team sport played on ice or a field, where players use sticks to hit a puck or ball into the opposing team's goal. In ice hockey, teams consist of six players, while field hockey teams have eleven. The game emphasizes teamwork, strategy, and physical skill, with players wearing protective gear in ice hockey to prevent injuries. Tennis is an individual or doubles sport played on a rectangular court divided by a net. Players use rackets to hit a felt-covered rubber ball over the net, aiming to score points by landing the ball in the opponent's court. The game can be played on various surfaces, including grass, clay, and hard courts, and is known for its competitive nature and athleticism.
