It’s not really a fifth equation. It is just a simplified version of the equation s=ut+0.5at2 for a very particular situation; when a body starts moving from rest or starts falling from rest as you are correctly explaining.

Dear Mr. Busuttil,
It’s Rebecca Grech from Grp 2B (1st year). It just dawned upon me that I hadn’t given you a reply with regards to the equations of motion. We were taught that there were five equations, the fifth one being s=at^2/2. This can only be used if and when the body starts at rest.
