How can an object have negative momentum?
An object can have negative momentum if it is moving in the opposite direction to a chosen positive direction. Momentum is a vector quantity that considers both the mass and velocity of an object, so moving in the opposite direction as chosen positive direction can result in negative momentum.
When is momentum negative in a physical system?
Momentum is negative in a physical system when an object is moving in the opposite direction of its defined positive direction.
What is the difference between positive and negative momentum?
The difference between positive and negative momentum is the direction that the object is going. Left and down are negative, right and up are positive. For example: if a ball is rolling to the left, it has a negative momentum.
Why two objects move in opposite direction one will have positive momentum and other negative momentum?
Quite simply, this means that momentum is a vector quantity; the direction is relevant. This is useful, for example, for calculations involving the conservation of momentum. Actually momentum is the product of velocity and mass, and velocity is also a vector quantity - thus, in this example, one object will have a positive velocity (more precisely: a positive component of the velocity along the x-axis, for example), the other, negative. Multiplying this velocity by the mass will also give a quantity which may be positive or negative (or rather, have positive or negative components).
How do you find the total momentum of 2 objects moving at the same speed in opposite directions?
To find the total momentum, you add the momentum of both objects. Since they are moving in opposite directions, you should consider one momentum as negative to account for the opposite direction. Mathematically, you can calculate total momentum by adding the individual momenta together.

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.
Is the momentum of an object always positive?
Depending on how you define it. Momentum is always given positive units, but sometimes when considered in a relative view, it can be in a negative direction making the overall value negative too (while mass is always positive, velocity might be in a negative direction where e.g. two masses are moving in opposite directions).
Is a net loss a negative or a positive?
You can consider any direction as positive, and the opposite direction as negative. However, in this case it is customary to call a gain "positive", and a loss "negative".
Is the velocity negative in this scenario?
In this scenario, the velocity is negative if the object is moving in the opposite direction of the positive direction.
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.
When does latitude become negative?
If you define one direction (for example, north) as positive, then the opposite direction is negative.
What can have positive or negative value depending on the direction of the change in position?
Velocity can have positive or negative value depending on the direction of the change in position. Positive velocity indicates motion in one direction, while negative velocity indicates motion in the opposite direction.
