What is positive and negative acceleration?
Positive acceleration occurs when an object's velocity is increasing over time, while negative acceleration (or deceleration) happens when an object's velocity is decreasing over time. Positive acceleration can be due to speeding up, turning, or changing direction, while negative acceleration is typically caused by slowing down or stopping.
When a car's velocity is positive and it's acceleration is negative what is happening to the car motion?
The car is slowing down
If a car is slowing down can its acceleration be positive?
No, if a car is slowing down, its acceleration is negative. Acceleration is defined as the rate of change of velocity, so if the car's velocity is decreasing, its acceleration is in the opposite direction.
Is retardation positive or negative acceleration?
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
When a car's velocity is negative and its acceleration is positive what is happening to the car's motion?
The car is slowing down
What is positive acceleration negative acceleration?
Positive is speeding up and negative is slowing down
What is negative and acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
What is positive and negative acceleration?

Positive acceleration can be due to speeding up, turning, or changing direction, while negative acceleration is typically caused by slowing down or stopping.
Difference between negative and positive acceration?
Positive acceleration ==> speeding up Negative acceleration ==> slowing down
When a car's velocity is positive and it's acceleration is negative what is happening to the car motion?
The car is slowing down
How can an object slowing down have an acceleration that's not negative?
If the positive direction was defined at the outset as the direction opposite to the direction in which the object happens to be moving just now, and the object is slowing down, then the acceleration is positive because, algebraically, the object's speed is increasing in the positive direction.
If a car is slowing down can its acceleration be positive?
No, if a car is slowing down, its acceleration is negative. Acceleration is defined as the rate of change of velocity, so if the car's velocity is decreasing, its acceleration is in the opposite direction.
Is retardation positive or negative acceleration?
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
When a car's velocity is negative and its acceleration is positive what is happening to the car's motion?
The car is slowing down
When velocity is negative and acceleration is positive what happens to an objects motion?
Its slowing down (but still moving).
Why car still accelerates after slowing down?
Acceleration is a change in velocity. Assuming a constant direction, if you're speeding up that is positive acceleration. If you are slowing down, that's negative acceleration. Either way you are accelerating.
Can a car have negative velocity and positive acceleration at the same time if traveling on a highway?
Yes.If the car is backing up, but slowing down, then its velocity is in the negative direction, and its acceleration is in the positive direction.
