Re-arrranging equationsMake ‘x’ the subject Re-arrranging equations
It’s all about opposites‘Inverses’ as we like to call them
If you make something the subject then….It will be on the left hand side of the equation and ‘equal to’ something
Make ‘a’ the subject of v = u + atTake ‘u’ from each side v – u = at Then divide by ‘t’ v – u = a t
But it isn’t ‘a = ….’ So flip it
‘flipped’ gives us a = v – u tv – u = a t ‘flipped’ gives us a = v – u t
Make ‘x’ the subject of v2 = u2 +2axTake away u2 v2 - u2 = 2ax Divide by ‘2a’ v2 - u2 = x 2a
Flip it! x = v2 - u2 2a
