# Acceleration Equation on the TI-89 | Every Step Physics

### Tension Pulling or Pushing on the TI-89: Video Transcript

This is a video on acceleration in physics

and ah given regarding maybe tension when you

something is pushing or pulling with some tension

let’s get started you press second alpha

to put the letters p h y s i c s in here and press alpha again to put the

open and closed parenthesis press enter and you are into my menu

we’re doing acceleration here you can see the number of choices you have

and we can go for all kinds of work all kinds of things in my menus

regarding physics and press two to get into acceleration

press one to get into the next menu for acceleration

and we have the choice of generally in a test your given or asked

to find acceleration and therefore you go to acceleration

in my programs and you scroll down to something with tension

here you have tension with ah coefficient of kenetic friction

so we’re going to do that one ah they give you mass

you have to press alpha before you enter anything into my program entry lines here

press alpha put in eight give you the choice of kilograms or grams

tension let’s say alpha fourty two newtons the angle is alplha maybe thirteen point five

degrees and the coefficient of kenetic friction might

be point one seven five

I always show you what you’ve entered so you can change it make sure you got it right

from what’s given I say it’s ok

here’s the formula you write this down on your paper

physics is scored on partial credit and class curve

so whatever you write down you get credit for

but you’re going to get one hundred percent on this problem

the unknowns are put in for that formula you’re doing the calculations just like you

would on paper

write everything down just like you see it and i give it to you in fraction format

and also in five rounded decimal points to meters per second squared

pretty neat huh every step physics dot com

go to my site buy my programs

and pass physics
