this is a TI-89 program app for the titanium calculator

and with regards to physics and with regard to angular speed

so let’s get started here, to get my main menu, you have to

press second alpha and put p_h_y_s_i_c_s letters in

and press alpha again and put the open and close parentheses

press enter and your into my menu

many many many things here that will help you through your physics classes

tests and homework

that’s what we’re interested in, is passing

physics

uh… but we’re going to go to angular spleed right now speed right now

and uh… w equals angular speed, two pi frequency rads per second

that’s the formula

i’ll ask you to put the formula in, you have to press alpha before you put

anything in the entry lines of

the entry things here, you’re going to put eight

if you put rpms in, the formula requires revolutions per second so it’ll

change it and show you that and you write that on your paper

and

divide it by sixty

and you get point one one three revolutions per second

and ask you if it’s ok in case you made a mistake or something

and here’s the formula and the

answer

point eight three seven seven six rads per second

pretty neat huh? every step physics dot com

go to my my site check out my programs

This is a video on the ti 89 titanium program app for physics with regards to physics equations in this case we’re going to tackle trajectories which are in many tests there is a trajectory of a baseball hit so let’s get started to get to my main menu you have to press second alpha and enter the letters p h y s i c s then press alpha again to enter the open and closed parenthesis press enter and you’re into my menu my physics menu there’s many many things here you can scroll down to atwood machine angular speed acceleration angular acceleration centripetal acceleration et cetera but we’re going to do a baseball hit and we’re going to enter out initial velocity you have to press alpha before you enter anything in my entry lines so let’s just do alpha nine meters per second initial velocity I ask you if it’s ok I say it’s ok so you can change it if you want ah you have these choices time to height time to ground time to maximum height we’re going to scroll to maximum height right here I show you the formula all step by step show you the equations and here’s the four point one two eight four meters for maximum height ah time to ground there’s one point eight three four nine seconds here’s the formula again minus g, minus nine point eight one meters per second squared and here’s time at maximum height point nine one seven four three seconds here’s the formula

et cetera all my programs are step by step pretty neat huh? everystepphysics.com check out my site enjoy my programs and pass physics
