* Decreases means the velocity gets *smaller*.

* Increases means the velocity gets *larger*.

Here's what happens when velocity changes:

Decreasing Velocity:

* Slowing down: If velocity decreases, an object is slowing down. This means it's moving at a slower speed or changing direction.

* Deceleration: Decreasing velocity is often called deceleration.

* Example: A car braking to a stop.

Increasing Velocity:

* Speeding up: If velocity increases, an object is speeding up. It's moving faster.

* Acceleration: Increasing velocity is called acceleration.

* Example: A rocket taking off.

Important Considerations:

* Velocity is a vector: Velocity has both magnitude (speed) and direction. So, a change in velocity could mean a change in speed, a change in direction, or both.

* Force: Changes in velocity always result from a force acting on the object. Think of pushing a box to get it moving faster or applying brakes to slow a car down.
