In the case of constant acceleration, the four physical quantities acceleration, velocity, time, and displacement can be related by using the equations of motion

$V$f=$V$i+$a$t

$d$=$V$it+½$a$t²

$V$²f=$V$²i+2$a$*$d$

$d$=½($V$f+$V$i)t

In equations, vectors were often represented as bolded letters to distinguish them from scalars. With the appropriate notation disclosed in recent years, arrows are now placed on top of letters to represent vectors. Vectors are mathematical objects that are comprised of a magnitude and direction. The arrow on top of a letter indicates the direction in which the vector is pointing. Additionally, the length of the arrow corresponds to its magnitude.
