Completed: Nov. 9,1998
LANGUAGE- TI-BASIC 
Calculator- Ti83

SORRY FOR THE LONG README I JUST HAD A LOT ON MY MIND ;)

This is another one of those math solver programs. So what's different between this and most other physics solvers. Well first of all this has got more physics topics covered in the actual program. (it's mostly mechanics but there is one on work/energy). The program is divided into subroutines so if u know  you don't wanna use for ex. the Projectile Motion section just delete the respective file. 

Oh and if u take a peek into the code u might see stuff like   If <snip>  Then :::  <-- for some reason my calc would give me a syntax error for no possible reason and this was the only way i could get it to work.

Instructions: Just go to the topics --> equation u want to solve then enter an 'X' (w/o ' ') in the input field of the term u want to solve for.

For example: let's say u want to use the equation v2^2-v1^2=2AD and u want to solve for v2
then just enter all the numbers for the other variables but when the prog asks for "Velocity2=" enter 
an    X    and the prog will solve for that variable.

Warning!!!!: Don't use this prog if u don't understand basic physics principles (especially vectors). So remember if the 'down' direction is negative then gravity= -9.8   not  9.8. And you can get answers like distance =  -50. This just means displacement is 50 in the negative direction (f.ex. down if u said g=-9.8) 

NOTE!!!!: I do not condone cheating of any kind. You can use this program to CHECK homework or do quick calculations but i wouldn't use it on a test if i were you. Oh and I will NOT be held liable if due to the use of this program you flunk your AP Physics exam, can't get into the college of your choice and end up becoming a 'squeegie' man.  


Topics/Files included:

Physics (this is the 'launcher' for the other files)--- Physics  666 bytes

Kinematics                	------ zknematc   768  Bytes 
Dynamics  (+inclined planes)    -------zdynamic   945 bytes
Work/Energy		  	-------zenergy    698   "
Projectile Motion         	-------zpmotion   1306  "

In total the 5 files are about 4400 bytes. (yes i know it's big)

Equations Solved:
Kinematic-      A= (v2-v1)/t
		D= v1t+(at^2)*.5
		2AD= v2^2-v1^2
Dynamics-
		F=ma
		Ft= impulse = delta momentum!= note: p' means delta p
		mv= p
	'Inclined Planes'		
			tan(theta)= u   (coefficient of friction)
			A= gsin(theta)- ugcos(theta)  
Energy-   Kinetic
	Gravitational Potential
	Work
	Power

Projectile Motion-
	"Air Time" (total time in air)   using   d=vcos(theta)t+(gt^2)*.5  (d=initial altitude! usually zero)    {same as t=-2Vsin(theta)/G}

	Total Horizontal Distance traveled:    d= -2V^2cos(theta)sin(theta)/G
	Vert. distance at 'T'  d= vsin0t+(gt^2)*.5
	hori. disance at 'T'   same as above but with cosine

	Graph it! will create a parametric graph of the projectile's motion (u must zoom to fit it urself)
