The tennis ball bounces on the ground, gets hit by the racket, and flies through the air. The racket is swung by the player and hits the ball, repelling it and sending it to the other side. The player runs around the court and swings the racket.   ]]> 2019-05-17 14:05:10 UTC https://padlet.com/ben_workman11/zk5y93yqpg8z/wish/361186277 ben_workman11 https://padlet.com/ben_workman11/zk5y93yqpg8z/wish/361196348 Friction can be bad and good in tennis. A player doesn't want  air friction against them because it could slow them down or mess up a serve. The players want friction against the ground so they don't slip.  ]]> 2019-05-17 14:27:55 UTC https://padlet.com/ben_workman11/zk5y93yqpg8z/wish/361196348 ben_workman11 https://padlet.com/ben_workman11/zk5y93yqpg8z/wish/361746474 A player serving tennis ball. ]]> 2019-05-20 14:18:03 UTC https://padlet.com/ben_workman11/zk5y93yqpg8z/wish/361746474 ben_workman11 https://padlet.com/ben_workman11/zk5y93yqpg8z/wish/361747089 A player hitting the ball with their racket.]]> 2019-05-20 14:19:26 UTC https://padlet.com/ben_workman11/zk5y93yqpg8z/wish/361747089 ben_workman11 https://padlet.com/ben_workman11/zk5y93yqpg8z/wish/361748104 Speed is important and you need it to win. When you serve a ball then you want speed so it's harder for your opponent to hit the ball back. If the ball is on the other side of the court, then you would need speed to get to the ball quick. ]]> 2019-05-20 14:21:03 UTC https://padlet.com/ben_workman11/zk5y93yqpg8z/wish/361748104 ben_workman11 https://padlet.com/ben_workman11/zk5y93yqpg8z/wish/361752266 Tennis player running to get ball.]]> 2019-05-20 14:29:26 UTC https://padlet.com/ben_workman11/zk5y93yqpg8z/wish/361752266
