PWEAS HALP ME (PHYSICS TUTOR WANTED)

[Childstar.]

Im fucking lost when it comes to re-arrangeing these equations for uniform acceleration (grade 11, physics), could someone help me?

I don't have anyone else to ask, dads not home for a few days, don't have a mom to ask, and my old tutor moved away...

 

[arandomname]

You could start by posting the equations...

 

[TechnoPotamus]

Food goes in
Poop comes out
You can't explain that.

physics.

 

[Deezy]

ask here, or u can pm me.

take a picture of the page and post it? or find an example on the internet somewhere and post the link.

 

[gabe.]

do this at least

 

[Deezy]

Tangent of V/T = amount of Acceleration

 

[H8CH]

Here's a good website full of lot's of useful shit - I even still use it now...

[J.M]

id be glad to help after you do so^

 

[Childstar.]

I need to isolate Aav

 

[arandomname]

I haven't learned it, but couldn't you just subtract Vi^2 and then divide by 2deltaD? That's the math part of me talking.

 

[Deezy]

VF/2Vi^D ??? derp

 

[.Blake.]

Vf^2 = Vi^2 + 2 Aav deltaD

 

[Childstar.]

an what i was attempting to do was divide Aav out and i would end up with something like this:

but then i don't know what to do from there...

 

[panojibber]

wat you doing

take

(Vf^2-Vi^2)=2AavD

(Vf^2-Vi^2)=(2D)Aav

(Vf^2-Vi^2)/(2D)=[Aav(2D)]/(2D)

(Vf^2-Vi^2)/(2D)=Aav

 

[arandomname]

If I'm not mistaken, wouldn't you not be allowed to do that? Becuase you didn't divide the Vi^2 on the other side by Aav.

Or maybe I just don't understand physics equations because all I've done in the past 2.5 weeks of physics class is build a rubber band car to teach us about physics and then today we timed our teacher on his motorcycle in the parking lot to try to learn about acceleration I think.

 

[Childstar.]

so is this right?

 

[arandomname]

If it follows all the rules of algebra, that would be right. You don't need to know physics to do it.

That's what I said in the beginning and I'm taking my first class of physics in the 11th grade.

 

[panojibber]

Looks good to me! Combining terms like that is a really useful trick that you'll see a lot in physics.

 

[CassiusClay]

Yes, that's right.

 

[BILL.COSBY]

im in grade 11 too, but i only took bio cause the only physics teacher is a huge gooch. have fun though!

 

[LDV]

I'd say that's right as well.

Go here http://www.khanacademy.org/ and watch some of the math and physics videos. I guarentee you will understand it. The way he teaches isn't like any teacher/professor, you actually understand it. It is awesome.
