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).
What else can I help you with?
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.
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 relationship between the direction of angular momentum and the motion of a rotating object?
The direction of angular momentum is always perpendicular to the axis of rotation of a rotating object. This means that as the object rotates, its angular momentum will also change direction, influencing its motion and stability.
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.
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.
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.
What direction will the momentum of an object always be going?
Away from the source.
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.
Why is the momentum of a roller skater is not conserved?
The situation is not quite clear. Total momentum is always conserved, but momentum can be transferred from one object to another.
What is the relationship between the direction of angular momentum and the motion of a rotating object?
The direction of angular momentum is always perpendicular to the axis of rotation of a rotating object. This means that as the object rotates, its angular momentum will also change direction, influencing its motion and stability.
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.
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.
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).
