Head heavy or Head Light?
An 89-gram badminton racquet with a head light balance will feel much lighter than an 89-gram racquet that is head-heavy. On the head-heavy racquet, the mass is further from the hand and feels heavier although the actual weight is the same.
This feeling can be calculated and is referred to as the Pick-up Weight or First Moment or Static Moment.
Formula:
(Weight of racquet X Distance from balance point to the hand) / 100
The higher the value of the first moment, the heavier the racquet will feel as it is held by the hand.
Experiment!
Will a 90-gram head-light racket with a balance point of 280mm feel the same as a 84-gram head-heavy racquet with a balance point of 300mm?
Time to measure some racquets and try it out!
