Positive acceleration = speeding up; speed increasing in the direction you're moving.
Negative acceleration = slowing down; speed decreasing in the direction you're moving,
or speed increasing in the opposite direction.
What else can I help you with?
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.
How is a negative acceleration different from a positive acceleration?
A negative acceleration refers to a decrease in velocity, while a positive acceleration refers to an increase in velocity. Negative acceleration occurs when the speed of an object is decreasing, such as when it is slowing down. Positive acceleration occurs when the speed of an object is increasing, such as when it is speeding up.
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.
Can both the velocity and acceleration be negative?
Yes, both velocity and acceleration can be negative. Negative velocity indicates movement in the opposite direction of a chosen positive direction, while negative acceleration indicates a decrease in velocity in the chosen positive direction.
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 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.
Difference between negative and positive acceration?
Positive acceleration ==> speeding up Negative acceleration ==> slowing down

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.
Does a softball have a positive or negative acceleration when it is thrown?
When a softball is thrown, it has a positive acceleration because its velocity is increasing with time as it moves through the air.
Can both the velocity and acceleration be negative?
Yes, both velocity and acceleration can be negative. Negative velocity indicates movement in the opposite direction of a chosen positive direction, while negative acceleration indicates a decrease in velocity in the chosen positive direction.
What happens when you put a negative acceleration and positive acceleration together?
You add them. For example, if a block is accelerating to the right at 2 m/s2 but is being slowed by friction accelerating the block to the left at 1 m/s2, then you can add the accelerations--positive is right and negative is left. The net acceleration would be 1 m/s2 to the right.
What is meant by de-acceleration?
de acceleration just means slowing down. Acceleration means speeding up. Actually any change in speed is considered to be acceleration. Slowing down is called negative acceleration or (de-acceration) and speeding up is called positive excelleration.
