Velocity = Vector value which stores direction and magnitude

Speed = length (or magnitude) of the velocity vector

Force = vector value which can affect the velocity of an object , it has direction and magnitude

Torque = magnitude of a force vector

VECTOR:

DOT PRODUCT:

dot product = length of vector A * length of vector B * cosine(Angle)

if length of 2 vectors = 1

    angle          =  arcCosine(dotProduct)
