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.


Is the retardation means zero acceleration?

No, retardation refers to a negative acceleration, which means the object is slowing down. A zero acceleration means the object is moving at a constant velocity.


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.


Why is retardation called negative acceleration?

Oh, dude, so like, when something is slowing down, it's actually experiencing negative acceleration. It's like the opposite of when you speed up, you know? So, they call it retardation because it's like saying, "Hey, slow down, negative acceleration coming through!" It's just a fancy way of saying things are getting slower, man.


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 positive acceleration negative acceleration?

Positive is speeding up and negative is slowing down


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..


Why is the value of retardation is negative?

Retardation, often referred to as negative acceleration, is considered negative because it indicates a decrease in the velocity of an object over time. In physics, acceleration is defined as the rate of change of velocity, and when an object slows down, its change in velocity is in the opposite direction to its motion. This results in a negative value for retardation on the acceleration scale. Thus, it signifies that the velocity is decreasing rather than increasing.


What is negative and acceleration?

Positive acceleration = speeding up. Negative acceleration = slowing down.


Difference between negative and positive acceration?

Positive acceleration ==> speeding up Negative acceleration ==> slowing down


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 an object slows down it has what acceleration?

Retardation or negative acceleration or deceleration.
