The rule that in the absence of outside forces the total momentum of objects that interact does not change?
law of conservation of momentum
Object A strikes object B the momentum of object B increase what happens to the momentum of object A?
You can't think of momentum as simply "increasing" and "decreasing" - you have to consider momentum as a vector.If in a collision one object's momentum changes by a certain amount, call it "a", the momentum of the other object will change by the opposite amount, "-a" - both "a" and "-a" are vectors that add up to zero. If you consider only the magnitudes of the momentum, by conservation of energy the momenta can't both increase - but they can certainly both decrease, when objects collide head-on.
What happens to the momentum of two objects which collide and stick together?
In a collision, a force acts upon an object for a given amount of time to change the object's velocity. The product of force and time is known as impulse. The product of mass and velocity change is known as momentum change. In a collision the impulse encountered by an object is equal to the momentum change it experiences.Impulse = Momentum Change. What happens to the momentum when two objects collide? Nothing! unless you have friction around. Momentum#1 + Momentum#2 before collision = sum of momentums after collision (that's a vector sum).
What is the theory of momentum?
The idea is that there is a quantity, "amount of movement", formally the product of mass x velocity, that is conserved. That means that the total momentum doesn't change, even if two objects collide, for example - any momentum lost by one object is gained by the other object.
What states that the total momentum of objects that interact do not change?
You have more or less described a law of physics known as conservation of momentum, which is not the same thing as the law of universal gravitation. The law of universal gravitation describes the way mass attracts other mass, and the law of conservation of momentum tells us that momentum is neither created nor destroyed. These two laws are not connected.

What does the impulse-momentum theorem state?
Impulse equals change in momentum. "Apex" The final momentum of any object (or collection of objects) must equal to its initial momentum plus any impulse imparted to the object (or collection of objects).

What never changes when two or more objects collide?
The total momentum of all the objects does not change when two or more objects collide together. An object that is smaller in mass can not have more momentum after the collusion.

What do you measure to find an objects inertia?
Inertia in physics is generally defined as resistance to change in velocity and it is measured as a change in momentum. (p is momentum, so change in momentum would be Δp, measured as Δp = m*Δv)
Does the law of universal gravitation state that the total momentum of objects that interact does not change?
No. The "total momentum" is related to Newton's Third Law. No, that is the law of conservation of momentum.
How are momentum and interia related?
Momentum, specifically linear momentum, defined as:p = mvwhere p=momentum, m=mass and v=velocityis a vector quantity that describes an objects motion in a given frame.Inertia, or the Principle of Inertia, is an object's resistance to a change in velocity. It is pretty much summed up by Newton's First Law of motion, an object at rest/ in motion will continue at rest/ in motion unless acted upon by an outside force.Momentum and Inertia are related conceptually in the way that any object with mass has momentum, if its velocity is zero than its momentum is zero, and inertia is that objects resistance to a change in its velocity.
Inertia is the resistance of an object to a change in its?
Inertia is directly proportional to an objects mass. Inertia is the desire of objects to continue doing exactly what they are doing. The greater the mass the greater the inertia.
Do heavier objects pick up momentum faster than lighte objects?
That really depends on the details of the experimental setup. However, impulse, which is change of momentum, is equivalent to force x time - that means that if a force is applied for a certain time, it will provide the same impulse (change of momentum) to objects of different mass. The more massive object's speed will change less, but this is compensated by its greater mass.
