Guitars are pretty cool, and you can do a lot with them! If you decide to play a guitar then the strings will vibrate through the bridge be amplified by the body. You could also throw a guitar if you wanted to! When you throw the guitar up in the air, the force you exert upon the guitar is exerted upon yourself so make sure its not too heavy! when you throw the guitar it will travel in a parabolic arch and have an acceleration of 9.81 downwards effecting the guitar. This is why the guitar will be destroyed if thrown, the net force is much stronger than the normal force a guitar usually withstands. Additionally the guitar will have the force applied to only a small part of the guitar upon its collision with the earth. In conclusion, please don't throw guitars!
