* Acceleration is the rate of change of velocity. Velocity includes both speed and direction.

* Decreasing acceleration doesn't mean stopping. It means the rate at which velocity is changing is getting smaller.

* Example: Imagine a car speeding up. It has a high acceleration. If the driver eases off the gas pedal, the acceleration decreases, but the car is still going faster. The speed continues to increase, just at a slower rate.

Think of it like this:

* High acceleration: The car is quickly gaining speed.

* Decreasing acceleration: The car is still gaining speed, but it's gaining it slower.

* Zero acceleration: The car is moving at a constant speed.

* Negative acceleration (deceleration): The car is slowing down.

Important Note: If acceleration becomes negative (deceleration), then the speed will start to decrease.
