Equation for u without v is also incorrect, should read u=(s-0.5at(squared))/t. You’d be better off starting with the original equations and rearranging them. This also helps reinforce the equations in your head and you become quicker in the exam! Great idea though!

The Equation to the right of the “U” is also wrong.
u = s – at^2 / 2t will provide incorrect results.
The correct formula should read:

u = (s – 1/2 at^2) / t

I wonder how many students have lost marks using this cheat sheet?
Although not many problems tend to ask you to calculate initial velocity “u” the sheet should be corrected if you want to leave it online.

Additional note:
2nd column, 3rd down, should read v = (2s+at^2)/2t
Both uses of the quadratic equation should be plus or minus.
4th column, 2nd down should be u=(2s/t) – v

When working U out without V Numerator should read 2S-at^2 🙂

and same with working V out without U

Is it 2s-at^2 or 2s+at^2 when finding V without U?

top right equation is incorrect, should be minus v^2

no its not other wise the answer is always 0

you rearranged s=u^2+V^2/2a wrong

This is confusing, i cannot figure out U without v and s

equation 4 along and 1 down should have a minus:

you have:

s = (t/2)(u+v)

therefore:

u = (2s/t) – v

The top right equation is wrong and should be corrected.

It should read:

s = (v^2 – u^2) / 2a

3rd and final correction from me (right hand column, 2nd row):

u = SQR (2as – v^2) is wrong as the number to be squared will be negative.

Correct formula should read u = SQR (v^2 – 2as)
