I know that there's 5 key equations for motion which is:(adsbygoogle = window.adsbygoogle || []).push({});

d = (vf+vi/2)t

vf = vi + at

d = vit + 1/2at^2

vf^2 = vi^2 + 2ad

d = vft - 1/2at^2

Correct?

But my teacher was confusing me today and he taught us these two other equations:

d = 1/2(vi+vf)t

d = 1/2at^2

What are these? Are they just other "rules of motion" like everything else?
