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 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.
Can an object have a negative acceleration and be speeding up?
Yes, an object can have a negative acceleration and still be speeding up. This occurs when the direction of the acceleration is opposite to the direction of the object's velocity. For example, if a car is moving forward with a velocity of 20 m/s and experiences a negative acceleration of -2 m/s^2 (deceleration), it will be speeding up while slowing down.
Is retardation positive or negative acceleration?
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
What are the three condition of the acceleration?
The three conditions of acceleration are speeding up (positive acceleration), slowing down (negative acceleration or deceleration), and changing direction (centripetal acceleration).
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.)
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
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.
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?
Yes, an object can have a negative acceleration and still be speeding up. This occurs when the direction of the acceleration is opposite to the direction of the object's velocity. For example, if a car is moving forward with a velocity of 20 m/s and experiences a negative acceleration of -2 m/s^2 (deceleration), it will be speeding up while slowing down.
Is retardation positive or negative acceleration?
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
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 are the three condition of the acceleration?
The three conditions of acceleration are speeding up (positive acceleration), slowing down (negative acceleration or deceleration), and changing direction (centripetal acceleration).
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.
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.
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 it true if an object is speeding up its acceleration is positiveif an object is slowing downits acceleration is negative?
Yes, that's correct. If an object is speeding up, its acceleration will be positive because the velocity and acceleration are in the same direction. On the other hand, if an object is slowing down, its acceleration will be negative because the velocity and acceleration are in opposite directions.
