We all know that tennis techniques have a lot to do with physics. One of Newton’s laws of motion explains that if you are traveling at 100 miles per hour, say in a car or a train, and chewing gum, that the gum is also traveling at 100 miles an hour, because it is at that moment, a part of you. How does that apply to tennis volleys?
What that law of motion tells you is that when you play volleys in tennis, when the ball connects to you (your racquet), the ball will take on the same motion as your body is making. So if you are stretching cross court, once you are connected to the ball, the ball will also travel cross court – and probably out.
So pay attention to the direction your body is moving when you connect with volleys in tennis. Your energy will carry the ball in the same direction you are moving. Remember this chewing gum principle! To offset this, try to play the ball back in the opposite direction that your body is moving so you make a successful shot.
