No. Negative acceleration means that you are decreasing in acceleration, like braking a car. Therefore, you can't be speeding up because speed and acceleration are connected. You can't travel at a faster speed if you are braking.

What is positive and negative acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
What is the definition of negative velocity?
Observe that the object below moves in the negativedirection with a changing velocity. An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration).
Is it true if an object is speeding up its acceleration is positiveif an object is slowing downits acceleration is negative?
No. Acceleration is the rate of change of velocity; any change of velocity qualifies, even if only the direction changes.
A negative slope on the velocity vs. time graph indicates that the object is not accelerating.?
It means the object is decelerating - slowing down rather than speeding up. You can think of it as negative acceleration.
When acceleration and velocity vectors are pointing in opposite directions the object is?
This would indicate negative acceleration, which would mean that the object in question is speeding up.

How do you find out the direction of angular accelaration?
The direction of angular acceleration comes from whether the angular speed of the object is clockwise or counterclockwise and whether it is speeding up or slowing down.The direction of the angular acceleration will be positive if the angular velocity is counterclockwise and the object's rotation is speeding up or if the angular velocity is clockwise and the object's rotation is slowing downThe direction of the angular acceleration will be negative if the angular velocity is clockwise and the object's rotation is speeding up or if the angular velocity is counterclockwise and the object's rotation is slowing downThe angular acceleration will not have a direction if the object's angular velocity is constant
Difference between negative and positive acceration?
Positive acceleration ==> speeding up Negative acceleration ==> slowing down
When does an object have no acceleration?
When it is stationary, or when the velocity is constant. If it is speeding up or slowing down, it has acceleration.
How can an object be accelerating if it's slowing down?
Acceleration doesn't mean "speeding up". It only means that the speed or direction of motion, or both, are changing. Speeding up is positive acceleration in the direction you're moving. Slowing down is negative acceleration in the direction you're moving, or positive acceleration in the opposite direction.
True or false Negative acceleration always means that a system is slowing down?
false A car can have a negative acceleration and be speeding up. A negative acceleration determines the direction of the acceleration A car with forward acceleration will speed up in the forward direction A car moving forward with a negative acceleration will slow down A car not moving with a negative acceleration will speed up in the backward direction A car moving backward with a negative acceleration will speed up in the backward direction
