Suppose there is a graph based on the x, y, z coordinates. From that graph, there is an equation, which is,

Referring from the same graph again, we get another equation,

Rectangular Components of Velocity and Acceleration 1

On differentiating the above equation (2.2),

  (Equation 2.3)

Rectangular Components of Velocity and Acceleration 2
Rectangular Components of Velocity and Acceleration 3

From the equation (2.3) you will get the scalar component of velocity which is,

vx = x , vy = y and vz = z(Equation 2.4)

Rectangular Components of Velocity and Acceleration 4
Rectangular Components of Velocity and Acceleration 5

From the above equation, scalar components of accelerations,

ax= , ay = , az=

, ,

, ,

Rectangular Components of Velocity and Acceleration 6
