It is physically impossible for an object to have a negative acceleration and yet be speeding up?

Not yet possible, maybe later.
Acceleration is the first derivative of the speed by definition. So this comes back to a mathematical question.
When do we have a first derivative negative? The only possibility is that the function has a negative slope, meaning in the case of the object trajectory, that the object's speed is decreasing.
If you could have objects decelerating while speeding up you should also think about accelerating objects winding down and steady objects wandering abound. As this was not easy to find conceptual representation for such situations, God just said to objects "thou will stop speeding up when you have a negative acceleration, capito?"
<<>> The answer could be 'yes' if the body has a negative velocity as well as a negative acceleration (relative to a given system of coordinates). In that case the speed is increasing even though the acceleration is negative.

What is positive and negative acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
Can an object have a negative acceleration and be speeding up?
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.
Is deceleration mean negative of acceleration?
acceleration is the speeding up of some type of matter. deceleration is the slowing down of some type of matter
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).
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.
What is positive and negative acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
What is negative and acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
What is positive acceleration negative acceleration?
Positive is speeding up and negative is slowing down
Difference between negative and positive acceration?
Positive acceleration ==> speeding up Negative acceleration ==> slowing down
Can an object have a negative acceleration and be speeding up?
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.
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
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.
Is deceleration mean negative of acceleration?
acceleration is the speeding up of some type of matter. deceleration is the slowing down of some type of matter
How can you recognise body getting into acceleration?
a body is accelerating if it is speeding up faster and faster. Acceleration is the change in velocity. or the change in speed. Slowing down is also acceleration but it is negative acceleration or de acceleration.
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).
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.
What is meant by positive acceleration and negative acceleration?
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.
