Okay, so in science I have a lab I need to complete about how the angle of an oject will efect it's fligh. After a lot time shearching everywhere on the internet I have not found one single thing. The only thing close to what I was looking for was on this site. So I was wondering if any one here could help me , or beter yet give me the adress to a site which will have information on how the angle of an object will effect the distnce it travels.
Thanks,(sorry about the spelling :) ) katie

just out of curiousity what grade are you in?
the angle with which an object is launched will determine how much of the initial velocity is in the x direction and how much is in the y direction

I am almost positive that it is 45 degrees.

I'm in grade nine, but I'm in this weird program called IB.
But, we were given differnt labs out, and mine was "how does the angle of an elastic band effect it's disatnce". I've done the experiment, but I need to find background info. I have all I need for enegry but I can't find anythign on how angles would effect it. I know a bit myself, but not neraly enough to do the lab D:

Maybe I read this wrong. I was responding by saying that 45 degrees will give optimum distance.
In the text book I used there was a page which clearly explained how the angle effected flight. I wish I still had it because I would scan it. Let me see if I can find something similar.

Yes, your right,but I don't know why. What I need to know is why that angle would be the best.
Sorry, D:

Here you go. This site is simplistic, but I think it should answer your question.

Start with your horizontal and vertical equations for projectile motion, see if you can derive some relation involving distance or velocity as a function of launch angle.
e.g. can you derive [tex]d_H = v^2/g*\sin2\theta [/tex] ?

ok Katie, the reason y u cant find anything is bc u mispell everything u type in lol jk. I had the same project to do and i need resources. i got 2 and just need 1 more!
one more tip use the spelling check :)

The range (the distance the object will travel in the X plane) is optimum at 45 degrees. However, there are two angles for each distance less than that. Let me elaborate:
If you launch the elastic at 55 degrees, and at 35 degrees, they will end up at the same spot. The only difference is that 35 degrees will travel less high, but nonetheless they should end up in the same spot on the ground. Same with 64, and 26 degrees. The two angles used must add up to 90 degrees.
