well surely theyre must be some reason i learned that in physics?

PMSL!!!!

i bow before you sir!

Could swing it around and work out the centrifugal force caused by the centripetal acceleration using cent f.=mw(sq)r and cent accn. = w(sq)r

Just dont let go of it or you will be watching linear motion in action as it flys across the room.

On a serious note normanlly it makes little difference, its the size that seems to effect the cost more. Try a few combinations out to see how the weight effects the cost then just guess. Ive sent stuff before and put it down as 1-2kg when its prob been twice that and never had any problems.

Couriers are too busy throwing them about damaging whats in the parcel to weigh it. lol

Or whilst in a lift traveling down at almost 10m/s

9.8m/s2(squared) lol

i should really keep studying all my phsics stuff, dont want to forget it, was my best subject


btw a kilogram bag of sugar weighs a kilogram...just saying lol

Got an exam on mechanics on tues, need to know it all
