Story by Cate Rounds, culture editor April 25, 2020. The use of metals and composites also allows the designers to make hollow frames — it is extremely difficult to make hollow wood components.

The sweet spots are influenced by the racket material and design, as well as the tension of the strings. We can demonstrate this using the law of conservation of momentum. between the outgoing ball speed and the incoming ball speed. If a ball strikes this racket at its centre of mass, the entire racket will recoil in the direction of the incoming ball in order to conserve momentum.
