My son is in 6 th grade and has a science project due next year. He has to begin by doing an outline now.

He wants to do something on weaponology with firearms /bullets. and perpetual motion. I cannot thing of a topic as the question he has to answer in his project. Any ideas are appreciated.

Hi buggirl,
Welcome to the Ask an Expert forum. There are many possibilities for projects dealing with projectiles. I would recommend that you and your son take a look at our Project Ideas Page:
https://www.sciencebuddies.org/science- ... deas.shtml
Projects dealing with "perpetual motion" are usually discouraged, because the overwhelming scientific consensus is that "perpetual motion" as most people understand it does not exist.
Good luck!
Chris

Welcome to the science buddies expert forum. For your project you could use
how does the angle affect the trajectory of an object being thrown?




Thanks,
