Yes, velocity of an object can be negative. This can be better explained with object in free space like aircraft. Aircraft's speed is measured relative to direction in which it is flying, its usually called airspeed. You might have seen in many modern fighter aircraft videos that's maneuvering, they fly straight up and then they fall vertically. During this vertical fall, aircraft is accelerating downwards & due to suction created in-front of pitot tube (Device used to measure airspeed) velocity measured is negative.

How are veloc ty and acceleration related?
Velocity and acceleration are related in that acceleration is the rate of change of velocity over time. If an object is accelerating, its velocity is changing. A positive acceleration means the object is speeding up, while a negative acceleration means the object is slowing down.
How can an object slowing down have an acceleration that's not negative?
If the positive direction was defined at the outset as the direction opposite to the direction in which the object happens to be moving just now, and the object is slowing down, then the acceleration is positive because, algebraically, the object's speed is increasing in the positive direction.
The slope of velocity time graph is changing what does it indicate?
A changing slope on a velocity-time graph indicates that the object's acceleration is changing. If the slope is increasing, the acceleration is positive, and if the slope is decreasing, the acceleration is negative. A flat slope indicates constant velocity.
Is acceleration the change of speed and or direction of an object?
These two cases are represented by "positive" acceleration. The opposite cases (slowing down in the positive direction or speeding up in the negative direction) are represented by "negative" acceleration.
The rate of change of velocity?
I think the answer to your question is acceleration.acceleration = change in velocity/ timea = deltav / tdelta is a triangle shaped character which means change in
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.)
How can you tell if acceleration is positive or negative?
Acceleration is positive when an object is speeding up in the positive direction (e.g., increasing velocity), and negative when the object is slowing down in the positive direction or moving in the negative direction (e.g., decreasing velocity). The sign of acceleration depends on the direction of the change in velocity relative to the direction of motion.
Is retardation positive or negative acceleration?
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
The change in an object velocity?
The change in an object's velocity is determined by its acceleration. If the object's acceleration is positive, its velocity increases; if it is negative, the velocity decreases. The larger the acceleration, the quicker the change in velocity will be.
Differentiate positive acceleration and negative acceleration?
A positive acceleration is a change in velocity such that the latter velocity is greater than the former velocity and is therefore going fasterwhile a negative acceleration or deceleration is a change in velocity such that the latter velocity is lesser than the former velocity and is therefore going slower.Now let us look at the equation of a uniform acceleration (the change in velocity is uniform):a = (vf-vi)/sIf the final velocity is greater, you will have a positive acceleration. If the initial velocity is greater, you will have a deceleration.
Can an object have both negative velocity and acceleration?
Yes, an object can have negative velocity and negative acceleration if it is moving in the opposite direction of the positive axis. This would mean the object is both moving backwards and its speed is decreasing.
If velocity is positive which would most likely yield a negative acceleration?
If an object is moving in the positive direction, a negative acceleration would most likely occur if the object is slowing down, such as when it is decelerating or coming to a stop. Negative acceleration indicates that the object's velocity is decreasing over time.
How is a negative acceleration different from a positive acceleration?
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.
What is the difference between positvie and negative acceleration?
Positive acceleration refers to an increase in velocity over time, while negative acceleration (deceleration) refers to a decrease in velocity over time. Positive acceleration occurs when an object speeds up, while negative acceleration occurs when an object slows 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.
What is the relationship between velocity and acceleration in physics?
In physics, velocity and acceleration are related in that acceleration is the rate of change of velocity. When an object's velocity changes, it experiences acceleration. If an object is speeding up, it has positive acceleration, while if it is slowing down, it has negative acceleration.
Which term explains whether and object velocity has increases or decreases over time?
Acceleration describes the rate at which an object's velocity changes over time. If an object's velocity is increasing, it has positive acceleration. If the velocity is decreasing, it has negative acceleration.
