Pickleball terminology

thumb| In ball sports, topspin or overspin is a property of a ball that rotates forwards as it is moving. Topspin on a ball propelled through the air imparts a downward force that causes the ball to drop, due to its interaction with the air (Magnus effect). Topspin is the opposite of backspin.

In racket sports a groundstroke, or ground stroke, refers to a forehand or backhand shot that is executed after the ball has bounced on the court. The term is commonly used in the sports of tennis and pickleball, and is counter to a volley shot which is taken before the ball has bounced. Groundstrokes in tennis are usually hit from the back of the court, around the baseline.
