![]() ![]() Since the racket’s strings are highly elastic, they exert a restoring force on the ball and help catapult it off again across the net, while the much more inelastic ball loses energy when it bounces on the court due to friction (though how much it loses depends on the type of playing surface).īut what about a specific shot like the backhand slice? Newton’s three laws of motion, for example, can be seen in action in every game – the second law (force = mass x acceleration) governs how a tennis racket hits a ball, with the force of the racket determining the resulting acceleration, and Newton’s third law tells us that the racket and ball exert equal and opposite force on each other.Įlasticity comes into play, too. Like the entire game of tennis, it all comes down to physics. With killer pace, the slice is often used by Barty as defense to return powerful shots, to set up attacks with her own booming forehand, or as a rhythm breaker. The shot has become her trademark, taking her to two major titles and lifting her to world number one. “I love to use my slice, I love to get creative with it, to use it offensively and defensively… Being able to use it with variety and have different options has been a massive part of my game through this last couple of years of my career.” ![]() In a post-game press conference, Barty said she’s learnt that her slice is a “weapon” for her. ![]() Roger Federer – if you’re back in Switzerland, yeah that’s right I said it, buddy. “Men’s, women’s tennis, it doesn’t matter. “Ash’s slice technique is arguably the best backhand slice technique in the world – period,” said Courier during Channel Nine’s broadcast of Barty’s quarterfinal win over Jessica Pegula. Though Barty played down the high praise, Courier has a point: while the world’s number one women’s tennis player possesses a whole range of dominating and technically sound shots, there’s something special – and deadly – about her backhand slice. This week, Australian Open commentator Jim Courier compared Ash Barty’s backhand slice to that of Roger Federer.
