In Newton's law ,
Force = Mass x AccelerationWhat is acceleration ?
Change of Velocity / time
To apply it in tennis, what kind of acceleration and for what ?
Acceleration of Racket head to achieve BOTH the TOP spin effect and the POWeR
To achieve TOP spin
Angular Acceleration (otherwise known as WHIP)
To achieve POWER
With these in mind, we need to achieve a Optimal mix of both to create the desired effect of both SPIN and POWER
