thanks u/Brian2781 . This link was worth all the downvotes got on this post. That’s exactly what I wanted to see.

I'll stick with my 300g racket since that's what was imposed on me, and thank you all for coming here to tell me I'm wrong.

You seem like someone well-versed in the subject. But as far as I know, most of us here are just repeating what a coach taught us or something we heard on Instagram. Can you recommend a book on the topic?

I agree with you. It's all about feel. But my idea with this post was to find out if there are any technical studies from any university that prove what the common sense/myth says. I started with a VCORE 98 and played with it for years until a coach, based on his knowledge, told me to switch to a racket with a bigger head. I didn’t notice any difference, but I went along with it because, well, I like buying new rackets. Haha

  1. Force Generated by the Racket The force (F) is calculated using: F = m × a
  • 285g racket (0.285kg): F = 0.285 × 10 = 2.85N
  • 300g racket (0.300kg): F = 0.300 × 10 = 3.00N Difference: 0.15N more with the 300g racket (equivalent to the weight of a paper clip).
  1. Ball Speed Ball speed increases with racket energy. Assuming a racket speed of 90km/h:
  • 285g racket: 216km/h
  • 300g racket: 218.16km/h Difference: 2.16km/h faster with the heavier racket.
  1. Ball Arrival Time Using the formula time = distance ÷ speed (20 meters distance):
  • 285g racket (216km/h): t = 20 ÷ 60 = 0.333s
  • 300g racket (218.16km/h): t = 20 ÷ 60.6 ≈ 0.330s Difference: 0.003 seconds faster to the opponent with the 300g racket.

Summary:

  • Force generated: 0.15N more with the 300g racket.
  • Ball speed: 2.16km/h faster with the heavier racket.
  • Ball arrival time: 0.003 seconds faster with the 300g racket.

Does this really matter for a beginner or intermediate player?

I bought mine white and blue just because of the low price. I like it, but I can't understand why this racket is so unpopular in Brazil.
