    Then'd we'd have to consider the gravitational pull of the sun, as well. What messy business!

    it takes minimum of 2 to tangles in the context of attraction

    Now, don't jump into relativity where the gravity of an object warps space and time around it. :p:D

    It is a messy business if one were to travel to Mars or other planets within our solar system. Okay, we are off topic. Let's discuss this in Chit Chat.

    again, that is why expression in newton is vague, it changes constantly even if the racket is not moving

    Yikes! This is geekily turning into a Star Trek convention.

    no gravity can warp space and time like your mind pete;):D:D:p:p:cool:

    another point to ponder. since every racket has a different CG (centre of gravity), how is it possible for the racket to be measured to the accuracy of 0.1grams? electronic balance will give a difference of 0.3grams when the racket is placed at different positions on the balance. unless they hang the racket from the tip and weigh them, then it may not be so accurate after all.

    Well, now we can just simply say that the range for the mass is because of the slightly varying amount of material in each racket that they can't control to the nearest .1 grams.

    Mass does NOT equal Weight -___-

    Mass is expressed in Kilograms or Grams.
    Weight is expressed in Newtons.

    Get your units right >__>

    Anybody who claims Weight is expressed in KiloGrams or Grams.

    racket should be expressed in mass. the reason is simple. not only are we interested in how heavy the racket weighs on a scale, whose weight we can calculate by f=ma, we are also interested in how much force we need to accelerate the racket, which is more accurately expressed in mass, also due to f=ma.

    so in other words, 99% of the stores out there are giving us the correct units, but not the correct label.

    I would think the majority of buyers would just go:

    XXXX: 90-94 gms

    ahh, perfect, that's the right one. Now, which color grip should I choose?

    and ponder no further than that.

    no showing the mass of the racket would be a big FAIL. no body is interested in knowing how much mass a racket has, we want the weight of the racket. using newtons is only for expressing forces in a scientific context. using grams is practical and straight to the point.

    lbs is reference to force already as we don't say lbs mass.

    we dont necessary have quote it in newton, expression in gram-force is suffice but we just lazy, and say 'gram' for short.

    ^yup, or thats at least how we pick rackets around here.

    I don't think anyone has really cared about this subject mainly because it doesn't matter if the companies are wrong because ALL of them are making the same mistake. :D
