Forces 83+ This is the first program that I made for a TI. Forces 83+ is, of course for TI 83+ you may try it on a TI 83 but I'm not sure if it works. This Program calculates the force, mass and acceleration of an object. It can even show you the equations. Feel free to distribute this program as long as you give me my credit. I hope that you enjoy my program. If you want me to make a program for you or hrlp you in doing one just tell me I will do it for free! you can contact me at spykerlr@yahoo.com
