Acceleration means: Any change of speed or direction.
Three simple examples are:
1). the car slowing down, because of either mashing the brake or going up a hill;
2). the car speeding up, because of either mashing the gas pedal or going down a hill;
3). the car going around a curve in the road, even of its speed doesn't change.

Is increasing acceleration the same as positive acceleration?
No. "Positive acceleration" means increasing speed. The acceleration is usually constantin typical Physics examples and applications.
What has to happen to a car's acceleration and velocity for a car's speed to increase and have a positive acceleration?
The velocity has to increase in a positive direction. The increase in velocity in a positive direction is a positive acceleration.
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 increasing acceleration the same as positive acceleration?
No. "Positive acceleration" means increasing speed. The acceleration is usually constantin typical Physics examples and applications.
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 has to happen to a car's acceleration and velocity for a car's speed to increase and have a positive acceleration?
The velocity has to increase in a positive direction. The increase in velocity in a positive direction is a positive acceleration.
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 are acceleration examples?
Examples of acceleration are change in speed, change in direction, or both.
What can positive acceleration called?
Positive acceleration could be called "speeding up" if you felt like it.
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.
Problems about positive acceleration?
Positive acceleration is an increase in velocity in the direction in which motion is being measured.
If objects get faster with time the direction of the acceleration is?
The acceleration is positive.
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
