How does the weight of the longbow affect the trajectory of the arrow?
Obviously the higher the poundage, the flatter the trajectory of the arrow. However, physics dictates that whatever the poundage of the bow, the trajectory of the arrow will never be totally flat (something to do with gravity). It is not really the trajectory that the archer should be bothered about but the poundage of bow that he/she could pull without being over bowed (a bow that is too heavy for the archer). If an archer is over bowed, they will tire quicker and will not be able to hold the bow on target in order for the aim to settle. A sixty pound bow is a much harder bow to use accurately for most beginners than a forty pounder.
