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.
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).
Does a stationary object have momentum?
No, a stationary object does not have momentum because momentum is the product of an object's mass and its velocity. If an object is not moving (velocity is zero), then its momentum will also be zero.
When does an object not have momentum?
An object does not have momentum when it is stationary or not in motion. Momentum is a product of an object's mass and velocity, so if either of these values is zero, the object's momentum will also be zero.

When two object is move in opposite direction one will have positive and other have negative momentum why?
Momentum is defined as a vector quantity; this means that the direction matters. Only if it is defined as a vector quantity do you have something called "conservation of momentum", which makes it very interesting for physics.
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.
Does a resting object have momentum?
No, a resting object does not have momentum because momentum is the product of an object's mass and velocity. Since a resting object has zero velocity, its momentum is also zero.
How to find the change in momentum of an object?
To find the change in momentum of an object, you can subtract the initial momentum from the final momentum. Momentum is calculated by multiplying the mass of the object by its velocity. So, the change in momentum is the final momentum minus the initial momentum.
The product of an object mass and velocity is called its What?
That's the object's linear momentum.
Will an object with mass have momentum?
Yes, an object with mass will have momentum. Momentum is a vector quantity that describes the motion of an object based on its mass and velocity. The momentum of an object is the product of its mass and velocity.
When ever an object is standing still the momentum is?
When an object is still it has no momentum. That is, the momentum is zero.
