I know that there's 5 key equations for motion which is:
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?
