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

Positive is speeding up and negative is slowing down
This depends on what the graph represents. If it is a graph of velocity on the vertical and time on the horizontal, then if acceleration is at a constant rate, the graph will be a straight line with positive slope (pointing 'up'). If acceleration stops, then the graph will be a horizontal line (zero acceleration or deceleration). If it is deceleration (negative acceleration), then the graph will have negative slope (pointing down).
Positive acceleration = speeding up. Negative acceleration = slowing down.
Positive acceleration ==> speeding up Negative acceleration ==> slowing down
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.
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.
Acceleration has a positive value if the velocity is increasing speed. Positive acceleration means the object is speeding up.
Retardation is a form of acceleration that is negative, meaning that the object is slowing down. Positive acceleration refers to the object speeding up.
When a softball is thrown, it has a positive acceleration because its velocity is increasing with time as it moves through the air.
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.
When you combine a negative acceleration (deceleration) with a positive acceleration (acceleration), their effects add up algebraically. This means that the resulting acceleration will depend on the magnitudes of the two accelerations and their directions. If the positive acceleration is greater than the negative acceleration, the object will still be accelerating in the positive direction. If the negative acceleration is greater, the object will eventually decelerate and change direction.
