What are the suvat equations and how would you apply them to a question ?

the four suvat equations are:s=ut+0.5at²v²=u²+2asv=u+ats=0.5(u+v)ts=displacement u=initial velocity v=final velocity a=acceleration t=time for most suvat equations you will be given 3 of the 5 quantities and will have to find out the 4th quantity. Normally students are caught out by worded questions so be careful when the question says the object starts at rest u=0 the object is free falling a=9.81 and other things like that.
