Velocity & Acceleration Diagram

is a fixed point.

Velocity diagram

Notation

• - Absolute velocity of point
• - Velocity of point relative to point

The above illustration is from Ruththiragayan, one of my friends.

Acceleration diagram

Notation

• - Absolute acceleration of point
• - Velocity of point relative to point

Here:

• - the radial component of the relative acceleration between A and B
• - the transverse component of the relative acceleration between A and B
