I'm required to do a science fair project this year and need some ideas. I was thinking about doing something that invovled my guns (preferably my AR or 10/22). Building a ballistic buffalo or a backstop are the ideas I have right now and seem to be easiset and best choices, however... I'm open for suggestions and ideas that would be cool to do for a project. Please keep them somewhat simple since I dont have access to fancy equipment, and I am in the 11th grade.

explain trajectory between to two diffrent rounds

explain trajectory between to two diffrent rounds


What could I do with explaining trajectory? I have to present a scientific or engineering problem, create a hypothesis, and then test it. Go into depth some more.

go into details of ballistic coeffecient. Show how two bullets of the same weight but different BC have different trajectories.

How tannerite works. Use the AR15.

I think this is true. if you drop a bullet and shoot a bullet from perfect horizontal (both from the same height and at the same time, they hit the ground at the same time. I don't know why, but I am in awe of this.


Is it true?

Do a balistic pendulum to show coservation of momentum. Basically, shoot a gun at a hanging piece of wood, so the bullet gets lodged in the wood. Measure how far it swings back. Repeat several times.

yes...

(NERD MODE ENGAGE)

Basically, horizontal velocity and vertical velocity are totally independant. That is, gravity affects both the bullet being fired and the bullet being dropped in the same fashion, causing them to fall at the same rate. The fact that the fired bullet moved in the x direction has nothing to do with what's going on in the y direction.

I saw a high speed photograph once of a handgun which claimed to prove that recoil started after the bullet had left the barrel. Of course, someone who actually shoots knows that not only the the gun begin to move when the bullet does, but the difference can be demonstrated in the different points-of-impact of various loads and bullet weights. It might be an interesting but simple and cheap way to demonstrate that the camera really does not see everything.
