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.
Why does a gunner feel a backward jerk when firing a gun?
This is conservation of momentum. You have the hot gases from the explosive charge along with the bullet moving out the barrel, away from the person. Momentum is mass times velocity. While the mass of the bullet and gases are small, the velocity is very high. So nothing was moving before the trigger was pulled, so net momentum is zero. After the trigger is pulled, the momentum is still net zero. Any momentum away from the gunner will have an equal momentum (the gun recoiling) toward him. Since the gun has much more mass than the bullet, the velocity is much less.
Definition of Momentum in physics?
The momentum of a moving body is defined as the product of its mass and velocity. Notice that since 'velocity' has a direction as well as a magnitude (is a vector quantity), momentum also has direction as well as magnitude. That's why two billiard balls, moving toward each other each with the same exact speed, can completely stop dead after the collision ... since their velocities are in opposite directions, their momentums are also exactly opposite, and add up to zero.
What is the society which some forecasters say that the world is moving toward?
We are moving toward a cashless society.

What the momentum between two identical balls traveling toward each other at thae same speed from opposites direction?
The momentum of one ball will be exactly the opposite of the momentum of the other ball. The total momentum in this case will be zero.
As a ball falls toward earth the momentum of the ball increases How would you reconcile this observation with the law of conservation of momentum?
The principle of conservation of momentum is not satisfied, since the sum of external forces is not equal to zero, if the ball falls the net force is equal to the weight, makes the ball Vary your speed and therefore their momentum.
Why do the planets stay in orbit rather then drift into space?
Planetary orbits are a balance between gravity, which pulls them toward the Sun, and inertia that keeps them moving forward in the same direction as they are going now. Inertia causes the planets to keep moving just as before, but gravity pulls them toward the Sun. As the planets fall toward the Sun, the inertia (more properly called "momentum") keeps making the planet miss the Sun as it is falling.
How does the planets orbit?
The planets orbit because of gravity and their momentum. They are constantly flying away from the sun, but at the same time are being pulled toward it by gravity. The end result is that they stay moving in a circular motion around the sun.
What is convesation of momentum?
The law of conservation of momentum states that momentum cannot be created nor destroyed, only transferred. In other words when you hit the wall with your fist, the wall gains the momentum your fist had while it was flying through the air toward the wall.
Bronco dives from a hovering helicopter and finds his momentum increasing Does this violate the conservation of momentum?
If you're only looking at Bronco, then it certainly seems to, doesn't it. That's because you're only looking at a part of the system, not the whole system. The whole system is the combination of Bronco and the Earth. When Bronco releases his grip on the helicopter's skid, and begins to fall, you have to look at both sides of the system. There is a pair of mutual, equal gravitational forces, attracting Bronco and the Earth toward each other, so both objects accelerate toward each other. The accelerations are in inverse proportion to the masses, so Bronco picks up somewhat more speed toward the Earth than the Earth picks up toward Bronco. But both of them are moving toward their common center of mass, and they're obviously moving in opposite directions. Bronco's speed multiplied by his mass is his momentum, directed downward. The Earth's tiny speed, multiplied by its large mass, is its momentum, directed upward. They're equal, and they're opposite, and they add up to zero, just like the momentum of the system before Bronco jumped. QED
