What will happen to the velocity and momentum of each ball when the small ball hits the heavier large ball?

The answer depends on the level of physics you have attained.
At the basic level, the collision is elastic. If the velocity of the small ball, of mass m, changes from u to v, and the initial velocity of the big ball, of mass M, changes from U to V,.due to the conservation of [kinetic] energy (and multiplying by 2), you get
m(v^2 - u^2) = M(V^2 - U^2)
Also, by conservation of momentum
mu + MU = mv + MV.
The small ball imparts some of its kinetic energy to the big ball. Depending on their relative masses, the small ball may rebound.
In a more sophisticated model the collision will be inelastic and some energy will be lost - converted to heat/sound.

Rocket works on the principle of conservation of?
linear momentum. A rocket works by expelling gases from one end at a very high velocity. The escaping gases have a very high speed and this with their mass translates to a very large momentum. Due to the principle of conservation of momentum the body of the rocket is pushed forward. If both the momentum of the gases as well as that of the rocket are added the sum is zero.
What objects have the most inertia?
Don't let speed or size fool you. The momentum of an object can be determined by multiplying the mass times it's velocity, so long as it's not accelerating. the product (kg x m / s) can also be written as the Newton second. This should easily solve your one dimensional linear situation. In real life however, rarely is a object moving in one dimension only at a constant rate. For real life applications, research angular momentum.
Can a moving object have impulse in itself?
yes moving objects have impulse
State and explain the law of conservation of momentum?
The law of conservation of momentum is Newton's 3rd law' The vectors sum to zero: 0 = F1 + F2 = dp1/dt + dp2/dt = d(p1 + p2)/dt =0. Thus, p1 + p2 = a constant, thus, the conservation of momentum.
What is the abstract noun of large?
The abstract noun form for the adjective large is largeness.The word 'large' is also a concrete noun as a word for a clothing size for persons who are heavier or broader than average; a garment in this size.
What is an example of an object with a small mass that has a large momentum?
That would depend on what you consider "large".The size of an object's momentum = (its mass) x (its speed).So, more mass and more speed result in more momentum.
Why does a slow-moving loaded truck and a speeding rifle bullet each have a large momentum?
Momentum is the product of velocity and mass.
What is the difference between a small momentum and a large momentum?
The larger the momentum, the harder it will be to stop it. Thus, the larger the force needed to decelarate the object. Since momentum is directly proportional to the velocity, the larger the momentum, the larger the velocity.
Why does a slow moving train have a large momentum?
Momentum = mass * velocity. The mass of a train is massive so it'll have a high momentum
In order for a small object to have a large momentun the object needs to be stationary true or false?
False. The momentum of an object is given by the mass times the velocity of the object. Hence, a low-mass object must have a large velocity to have a large momentum.
What has more inertia a large truck or a small car?
momentum is velocity multiplied by weight so if a small car weighs less than a large truck then it just needs to go faster to aquire the same momentum.
What is the relationship between velocity and inertia?
Newtons First Law of Motion states that an object with a given momentum will continue to posses that same momentum until the object is acted on by a force in which case it will undergo a change in momentum. Inertia is a measure of an objects tendency to resist a change in momentum. Massive bodies have a large inertia. If a massive body is in motion its momentum is given by the product of the mass and the velocity of that body. Newtons first law says that if a force acts on this body its momentum will change. But since the body has a large inertia this change is small. For example, if a small space pebble collides with a large asteroid that has a constant velocity and thus constant momentum, the force is small relative to the inertia of the asteroid so the momentum only changes a little bit.
Is the momentum of a large bus greater than less than that of a small car traveling at the same speed?
Momentum is a function of velocity and mass, therefore, assuming a "large" bus has more mass than a "small" car the bus would have more momentum since the velocities are the same.
How can a slowly docking boat and a speeding rifle bullet both have a large amount of momentum?
Momentum = mass * Velocity. Boat has large mass but low velocityBullet has small mass but high velocity.Momentum is a function of speed and mass. A slowly docking boat has a low speed, but the boat will have huge mass, therefore the momentum will be a large amount. The bullet has very low mass, but huge speed, and so, again, the momentum will be large.
Would a large mass with high velocity have more force than a smaller mass with same velocity?
Yes. There are two slightly different definitions of "force". Kinetic energy is calculated as 1/2 * mass * velocity squared, or 1/2mv2. Momentum is mass times velocity, or mv. When you simply say "force", you're probably thinking of momentum. But in either calculation, a large mass will have more force than a smaller mass.
Can an elephant have the same momentum has a golf ball?
Momentum, in classical terms, is defined as mass x velocity. So, theoretically, an elephant could have the same momentum as a golf ball if the golf ball (small mass) is moving very, very fast, and the elephant (large mass) is moving very, very slowly. If the product of the mass x velocity is the same, then the momentum can be the same.
Tennis ball have momentum?
Momentum is calculated by taking the product of mass times velocity. Thus, a moving tennis ball would have a nonzero momentum. However, since a tennis ball has a relatively small mass, it would need to have a high velocity in order to have a large value for its momentum. Since velocity is a vector (having both a magnitude and a direction), momentum is also a vector. When a tennis player hits a tennis ball with his racket, he imparts a force onto the tennis ball, which changes the direction of its momentum to return it over the net. (The value for this change in momentum is called impulse, which is equal to the product of the force applied and the time for which it is applied.)
