* Acceleration: Acceleration is the rate of change of velocity. Negative acceleration means the velocity is decreasing.
* Velocity: Velocity has both magnitude (speed) and direction. Negative velocity simply means the object is moving in the opposite direction of whatever you've defined as positive.
* Speed: Speed is the magnitude (absolute value) of velocity. It only tells you how fast something is moving, not the direction.
Scenario:
When acceleration is less than zero (negative) and velocity is positive:
* The object is slowing down.
* Its speed is decreasing.
* The object is still moving in the positive direction, but its velocity is getting closer to zero.
Example:
Imagine a car moving forward (positive velocity) but applying the brakes (negative acceleration). The car slows down, meaning its speed decreases, but it is still moving in the same direction (forward) until it comes to a stop.
