If an object traveling in one direction has a positive velocity what kind of velocity would the same object traveling in the opposite direction have?

Regardless of the direction being travelled, any object on the move has a positive velocity, even if it is moving backwards, because velocity is the measure of the rate of movement in a given direction.
Compare: A car is traveling forwards on a highway at 100 km/h. How fast is it travelling?
If it turns round (or even it doesn't turn round, but just reverses) and travels at 100 km/h, how fast is it travelling? The answer is 100 km/h in both cases. (But reversing on a highway and travelling at 100 km/h is not recommended!)

When velocity is zero and acceleration is negative what happens to the object in motion?
It accelerates in the opposite direction. Its velocity increases in the opposite direction to the direction that has been assigned positive.
Can momentum have a negative velocity?
No, momentum can not have a negative velocity. Velocity is the rate of motion of a body from one position to another position in a particular direction. Bodies traveling in opposite directions may appear to have a negative velocity in relationship to each other but any amount of velocity is positive.
What does positive velocity means?
is moves with a constant velocity in the positive direction......
What does it mean when the change in velocity is negative?
It means deceleration or slowing down and there is a force operating against the motion.
Is retardation positive or negative acceleration?
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
When angular velocity decreases the direction of angular acceleration is opposite to angular velocity .why?
Take the velocity to be in positive direction. Positive acceleration increases velocity and they are in the same direction. Negative acceleration reduce velocity and they are in opposite direction. It does not matter if the motion in linear or anfular.
When velocity is zero and acceleration is negative what happens to the object in motion?
It accelerates in the opposite direction. Its velocity increases in the opposite direction to the direction that has been assigned positive.
When velocity is negative and acceleration is zero what happen the object in the motion?
It accelerates in the opposite direction. Its velocity increases in the opposite direction to the direction that has been assigned positive.
Can a speed of a body be negative?
The 'speed' of a body cannot be negative. But if you are stating the 'velocity' then it can be negative. Negative velocity means it is going opposite to the direction that you decided to call the positive direction.
Can a car have negative velocity and positive acceleration at the same time if traveling on a highway?
Yes.If the car is backing up, but slowing down, then its velocity is in the negative direction, and its acceleration is in the positive direction.
Can momentum have a negative velocity?
No, momentum can not have a negative velocity. Velocity is the rate of motion of a body from one position to another position in a particular direction. Bodies traveling in opposite directions may appear to have a negative velocity in relationship to each other but any amount of velocity is positive.
How do you find the final velocity if the acceleration is negative?
It depends on what information you have. Also, velocity can be negative - it just means that the object is travelling in the direction opposite to the positive direction for the velocity vector.
What does positive velocity means?
is moves with a constant velocity in the positive direction......
What does it mean when the change in velocity is negative?
It means deceleration or slowing down and there is a force operating against the motion.
Is retardation positive or negative acceleration?
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
How is the absolute value of velocity speed?
Velocity is a vector and its magnitude depends on the direction. If it is positive in one direction, going in the opposite direction it is negative. But speed is a scalar and does not depend on the direction. It has the same value, whatever the direction. That is how the absolute value of velocity is speed.
What is the physical meaning of a negative average velocity?
It means that an object with a negative average velocity is moving in the opposite direction (of course according to the chosen positive direction of the predefined frame).
