GUYS. I have no idea how to extract T and make it the subject. Which equation am I using and how am I to make T the subject ? I need help so bad right now. Thank you :-)

I'm just asking in general. does it matter what the question is ? I just literally haven't got a clue how to make T the subject of an equation ...or which equation to use. Pls help someone in need

I would recommend writing out S U V A T on your paper, under them writing the value if it's known, an 'x' if it's not given and not of interest, and a '?' if it's what you're trying to find. Then you think of the equations and which one has everything you need.

Have I got this right ? I can't understand ...is it depending on the question which equation to use to make T the subject ?or can you use the same equation to find the value of T regardless of question

Do you know how to rearrange algebraic equations?

Call me a thick **** but no I genuinely don't. I understand the other equations it's just when rearranging I get jumbled up. Lol

When I was in sixth form the school provided some after school catch up lessons for 'maths for science' which gave people who were not doing maths or needed to catch up a fighting chance.

There are resources like this on the internet which help and I would consider asking for help from your teacher.

Like I'm fine with everything else and I'm barely struggling with maths. I know maths is still a struggle for me but I can do it and it doesn't take me long to figure it out ...my strong point has never been rearranging equations. And this SUVAT crap is just so annoying right now I just need an explanation

Using SUVAT it would depend on the question as to how to re-arrange for T as the subject. Reason being you could get given different variables for different questions, so you can't use the same formula.

For example, if you were given initial speed, final speed and distance travelled then you would need s=[(u+v)/2]t; however if you were given acceleration instead of distance then you would need v=u+at.

Hope that helps.

edit: If you're struggling in general with re-arranging equations then I have explained a bit about the principles of re-arranging equations here: http://www.thestudentroom.co.uk/show....php?t=3463387

With what spotify said about (u+v)/2, when you have distance, initial velocity and final velocity you need to find the average of the velocities.
