* Velocity is a vector: Velocity has both magnitude (speed) and direction.

* Direction of motion can change: A particle can be moving in one direction and then change its direction. For example, a ball thrown upwards has an initial upward velocity, but its velocity changes direction as gravity pulls it back down.

* Acceleration: If a particle is accelerating, its velocity is changing, even if its speed is constant. Think of a car turning a corner at a constant speed – the car's velocity is changing because its direction is changing.

In summary:

* Velocity is the rate of change of position *and* direction.

* Direction of motion is the path the particle is taking.

* While the direction of motion can influence velocity, they are not always the same.
