This is a TI-89 titanium program app in this video angular acceleration to get to my programs you have to enter second alpha physics and then press alpha again to enter the open and closed parenthesis, press enter and you’re into my menu, been my menu there’s many things in this menu you can see atwood machine, two pulleys and cord uh… beads on a wire, bulk modulus car catches truck,, center of mass

vectors basically many many things that are on the test we’re going to do acceleration and we’re going to find acceleration here first and then we’re going to choose angular acceleration notice there’s centripetal

acceleration and tangential acceleration also we’re gonna find angular acceleration and you’re given choices sometimes in a test they give you velocity initial velocity final velocity or and initial speed or final speed if it’s at rest of course it’s zero for one of the other and we’re going to do number one here

and you have to press alpha before you enter anything in my program for the enter alpha five it gives you the choice for inches centimeters or meters let’s say it’s centimeters uh… angular speed alpha nine

start with r p m’s if you put r p m’s in the formula it needs revolutions per second so i show you how to change that here and then we’re going to enter angular speed for the final angular speed alpha let’s go

let’s go alpha four a r p m’s again i show you how to change it and then alpha six seconds I show you what you’ve entered you can change it if you want if you made a mistake or something and we’re gonna i show you the angular initial angular speed because you’ve got to change that to radian so show you how to do that two pi radians and the final is change the radians again for the formula and then your acceleration is is this amount here radians per second you write all this on your paper to get a hundred percent on the problem pretty neat huh? check out my programs pass physics every step physics dot com

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
