Can any one explain to me what the 2nd equation of motion is used for?
i can't find any examples were it is used
btw: this is AS edexcel maths
u= initial velocity
v= final velocity
It is used to find any of these... And you use it in Newton's Laws of Motions, Forces...
Or am I not answering your question?
Sorry, I take AS AQA maths soo... :P
Just trying to help..
you sort of answerd my question thanks, i am just a bit confused as to if there are any special situations when the equation has to be used, because there are other options most of the time that are easyer to use,
do you understand wwhat i mean?
Yeah I get it. Usually we tend to use the other easier ones. But some situations force us to use just one equation. For example:
s = ut + 1/2at^2 has no 'v' in it. So if a question does not provide 'v', you'll be forced to use this specific equation. It's the same with the other ones.
s = vt - 1/2at^2 doesn't have 'u'
v = u + at doesn't have 's'
And so on. Does that help?
yeh it does, thanks alot
i hate you all
emily that is really nasty. i reckon this girl has issues, she should see a councellor.
Or she could have been expressing her hate for maths. :)
