A positive acceleration is a change in velocity such that the latter velocity is greater than the former velocity and is therefore going fasterwhile a negative acceleration or deceleration is a change in velocity such that the latter velocity is lesser than the former velocity and is therefore going slower.
Now let us look at the equation of a uniform acceleration (the change in velocity is uniform):
a = (vf-vi)/s
If the final velocity is greater, you will have a positive acceleration. If the initial velocity is greater, you will have a deceleration.

What is positive and negative acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
How is a negative acceleration different from a positive acceleration?
Actually, it depends on how you define the coordinate axes, but usually when moving forward, negative acceleration decreasesspeed, positive acceleration increasesit.
Does acceleration have a negative or positive value if the velocity is increasing speed?
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
Is retardation positive or negative acceleration?
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
When can you used the positive acceleration due to gravity and negative acceleration due to gravity?
If you define the "up" direction as "positive", then the acceleration is negative, because it is downward. If you define "down" as positive, then acceleration is negative. You can use any convention; just be sure to be consistent within a particular calculation, to avoid errors.
Can there be a positive acceleration and a negative acceleration?
Yes, acceleration can be positive and negative because acceleration is a vector. It has both direction and magnitude. The direction is what makes it positive or negative. Negative acceleration is usually called deceleration.
What is positive and negative acceleration?
Positive acceleration = speeding up. Negative acceleration = 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.
Does a softball have a positive or negative acceleration when it is thrown?
positive
Difference between negative and positive acceration?
Positive acceleration ==> speeding up Negative acceleration ==> slowing down

What is positive negative and zero acceleration is?
positive acceleration is when things speed up; negative acceleration is when things slow down; and zero acceleration is when things do not speed up or slow down, this is called constant speed, or no change in velocity.
When acceleration upward or downward direction is taken positivw or negative?
If it is gravitational acceleration then it it is positive in downward and negative in upward direction..if it is not gravitational acceleration then it is depending upon the value of acceleration.
