retardation is nothing but the decrease in speed. so if the increase in speed can be taken as positive then for sure decrease in speed can be taken as negative acceleration.

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.
How can you find the retardation of a curve in a speed time graph?
Calculate the gradient of the curve which will give the acceleration. Change the sign of the answer to convert acceleration into retardation.
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.
Can a car have negative velocity and negative acceleration?
It cannot have negative velocity, it can have negative acceleration.
How can you have negative acceleration but not negative speed?
The negative part in negative acceleration is indicating direction, as acceleration is a vector quantity. Speed however, is a scalar and has magnitude only and therefore cannot be negative. An example could be -2.6ms-2 meaning that there is an acceleration of 2.6ms-2 but in the opposite direction to other vectors.
What is acceleration and retardation?
acceration means rate of change of velocity and if that acceration is negative then it is called as retardation
Is retardation positive or negative acceleration?
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
When an object slows it has what acceleration?
Retardation or negative acceleration or deceleration.
When an object slows down it has what acceleration?
Retardation or negative acceleration or deceleration.
An increase of speed during a given interval of time is called negative acceleration?
No, it's only the acceleration. By (-)ve acceleration ,it means retardation or deceleration..

Which is also called as retardation or deceleration?
Deceleration is a special case of what physicists call "acceleration" - a rate of change of velocity.
What is a negative acceleration called?
You'll find a lot of people who call it "deceleration". But in real Physics, there's no such thing.There's only positive or negative acceleration, depending on whether the acceleration is inthe same or opposite direction compared to what you decided to call the positive direction.Negative acceleration is sometimes, but not always, associated with something that's slowing down.
What is negative acceleration also called?
Negative acceleration is also called as deceleration.
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.
How can you find the retardation of a curve in a speed time graph?
Calculate the gradient of the curve which will give the acceleration. Change the sign of the answer to convert acceleration into retardation.
If acceleration is 8 what is value of retardation?
Zero
