Velocity Equation

v = change in position/time = ∆x/t

Distance

How far an object has traveled from initial to final position

Displacement

The change of an object's position

Speed

How fast an object is traveling

Velocity

The rate of change of an object's position

Distance vs Displacement

Displacement has direction, Distance does not

Speed vs Velocity

Speed has only magnitude, Velocity has magnitude and direction.

Magnitude

Size

Scalar
