Final answer:
In tennis, a high-arcing shot deep into the opponent's side of the court is known as a lob. This technique is part of the game's strategic plays and requires understanding of the racquet's sweet spots for effective performance.
Step-by-step explanation:
In tennis, a high-arcing shot hit deep into the opponent's court is called a lob. This strategic shot is used to send the ball over the head of the opposing player, particularly when they are positioned close to the net, making it difficult for them to hit a good return. The arcing motion of a lob is a type of curved path, which is considered two- or three-dimensional motion, and requires players to account for the spin and bounce as well as accurately predict the trajectory of the ball to execute effectively.
Tennis racquets have what are called "sweet spots," which refers to areas on the string bed where contact with the ball will cause the least amount of vibration to the player's arm. When a tennis ball hits the sweet spot, it results in a more comfortable and effective shot for the player. Understanding the playing equipment's sweet spots can greatly influence a player's performance and the outcome of the match.
