It depends on whether they are both moving or if one is stationary and the other is moving.

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.


What is a momentum of an object of mass 'm' moving the velocity v?

Momentum is mass times velocity. Note that velocity and speed are not exactly the same thing. Velocity is a term used in physics to define both the speed and the direction of a moving object, so if two objects are moving at the same speed but in opposite directions, they have opposite momentum.


How do you calculate the new velocity so that momentum remains same?

apply conservation of momentum theory- m1v1=m2v2 where m1 is the initial mass, m2 is the final mass, v1 is the initial velocity and v2 is the final velocity.


How does a rocket travel?

By expelling hot gasses extremely fast from the rocket nozzle. Due to the conservation of momentum, expelling mass at high velocity causes the rocket to gain momentum and therefore velocity.


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).


Why does velocity stay constant with decreasing momentum?

As far as we can tell, it doesn't. Momentum is defined as (mass) times (velocity). There appear to be only two ways in which momentum can decrease: either the mass has to magically evaporate, or else the velocity has to decrease. Since mass conservation is a nearly fundamental law of nature, that leaves us with velocity as the only way to change the momentum of a moving body.


Conservation of linear momentum explain?

The conclusion for a lab about the conservation of linear momentum is exactly that. Linear momentum is conserved. Momentum p = m*v is a product of mass and velocity. The larger the mass or faster the velocity, the higher the momentum. It takes prolonged force to stop it. Also, if a closed system exists that is not affected by dissipative forces, the total momentum of the system will remain. In a collision between two objects, momentum is conserved.


What is does momentum have to do with bottle rockets?

When it comes to water bottles, there is downward momentum, which creates an upward momentum. The reason for this is the conservation of momentum. That's why the water bottle is driven upward. The downward momentum is created by the water mass times water's velocity.


What is the difference between law of conservation of energy and conservation of momentum?

conservation of momentum depend upon mass and velocity.by the formula its given as m'.v'=m.v but the energy have void area it apply in themodynamics,revolution of planet in every physical universe..where is velocity is not taken in count there no momentum but there have some specific energy of body


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 collision exemplify the law of conservation of momentum?

The vector sum of momenta before and after the collision is the same. One way to visualize this is that if one of the colliding objects changes its momentum (mass x velocity) in one direction, then the other colliding object must needs change its momentum in the opposite direction - by the same amount, except for the direction.
