A Level Physics Coursework: Physics behind Archery.?

Question

Hi, recently i've been assigned my latest A Level Physics coursework. The teacher told us that this particular coursework would be a report (a non experimental) on any topic in physics we prefer and make a presentation of it. After some brainstorming, i decided to check out the physics behind archery. The reason is mainly due to fascination of it. First thing about a report is to find an aim, hence i have been thinking of what kind of things i could find from archery that is physics related. I first thought of bows and crossbows and whether in terms of physics, i could compare both and somehow state which is better at what category( such as accuracy, range, power etc).
But the main reason i am writing this on yahoo answers is because i lack alot of information in this physics field. I would need alot of data and information regarding how a bow actually works and the types of bow - how each type differs from others etc. Therefore, i am looking for an answer which would tell me a bit of this topic, any links would be appreciated. Also i would like any advice or opinions on whether it is wise to make a report on this topic. Thanks!

Answer 1

The bend on the bow when in use by an archer is usually a constant . All the elastic energy is from the bending of the bow material which these days is a composite material (laminations of plastic/ wood). If you vary the amount that the bow is drawn ( bent) then you could see if increasing the draw produces a greater force and so a greater range at a constant angle. You may be able to rig up a device to measure the initial velocity that the arrow leaves the bow. It is well known that cross bows can be made a higher draw weight than a traditional longbow so will have a greater range - it could be an interesting project but difficult to do in practice - but as a paper exercise it will give you plenty of scope for extending your investigation

Answer 2

this could be a diverse style question that many will forget approximately approximately. you're able to break that down into separate ones. Filters will take in greater of the frequencies which could come back with the aid of. and watching colour remains between the main suitable thank you to be certain this is purity and frequency. The human eye is a ordinary classification device. as a ways through fact the LDR is in touch, you're able to nicely known its performance at a number of frequencies to get a real readout. to your e mail: the problem is that obtaining filters that are organic adequate would be (just about) impossible, diffraction gratings or prisms don't have that problem. diverse filters will in basic terms worsen that problem, through fact the impurities will upload up.

Ouch! You nearly got me there pal.
