(1) Decide on a direction that you will consider positive. (2) Calculate the momentum of the object that travels in the "positive" direction. (3) Calculate the momentum of the object that travels in the "negative" direction (the momentum should be negative). (4) Add both numbers algebraically.

What is a example of a momentum of zero?
An object at rest. Actually that's the only possible example for a single object. For two objects, you can have objects moving in opposite directions; for example, one may have a momentum of +100 units, and the other, a momentum of -100 units.
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.
What depend on objects mass and velocity?
a moving objects momentum
Why do objects start or stop moving?
Objects move if they have momentum. Momentum is gained via an applied force. Therefore objects start or stop moving when a net force is working on them.
What moving object depends on the objects mass and velocity?
That's the object's linear momentum.

When can the momentum of two moving objects be cancelled?
The momentum can be cancelled when the objects are equal and opposite in momentum, 0= p1 + p2, thus p1=- p2. Newton's 3rd law.

Why do electron n positron move in opposite directions in pair production and how does momentum is conserved when they move in opposite directions?
They move in opposite directions when in a magnetic field because they have opposite charges. The force on a particle depends on its charge -- make the charge completely opposite, and the force on it will be completely opposite. Momentum is conserved when they move in opposite direction (that is, in their center of mass frame) because their respective masses are identical. One electron mass moving in one direction plus one electron mass moving in the opposite direction means a total momentum of zero. The system begins with zero momentum and ends that way.
What depend on objects mass and velocity?
a moving objects momentum
All moving objects have?
All moving objects have Momentum.
Why do objects start or stop moving?
Objects move if they have momentum. Momentum is gained via an applied force. Therefore objects start or stop moving when a net force is working on them.
What opposes motion and causes moving objects to slow down?
concervation of momentum concervation of momentum 2nd Answer: Well, not really, no. Friction causes moving objects to slow.
How will balls move if they collide and stick together?
Consevation of momentum applies. The final compond mass must have the same momentum as the net momentum of the two balls before the collision. Remember, momentum is a vector and direction is important. For example if the two balls are moving toward each other with the same momentum, the net momentum is zero because they are moving in opposite directions. So the compound ball will not move. Or, if ball 1 is moving left and has a greater momentum then ball 2 ,moving right, then the compound ball will move left. Its momentum will equal the difference between the two momentums because when you add two vectors in opposite directions you subtract their magnitudes. Mechanical energy (potential + kinetic) is not conserved in this collision because some mechanical energy is lost as heat in the collision.
