Concepts and Reason

Velocity of a fluid particle is a function of location and time. Velocity is a vector which has both magnitude and direction.

The acceleration of a fluid particle is the time rate of change of velocity.

Fundamentals

The velocity vector for a fluid particle,

The acceleration vector for a fluid particle in three dimensional flow,

The scalar components of acceleration vector,
