The total amount of momentum of a group of objects does not change unless outside forces act on the objects?
Momentum
Which physical quantity is measured by rate of change of momentum?
Force and rate of change of momentum (both vector quantities) are cause (force) and effect (rate of change of momentum). Newton's second law of motion equates the two quantities, but they are not identical. There is a distinction in that forces derive from interactions between objects (gravitational, electrical, magnetic...) while momentum changes in response to the net force acting on an object or system.
What are the three quantities that determine gravitational potential energy?
The mass and distance (weight and height) determine the potential energy. A third factor can be the relative motion of the objects, which does not change the potential but may determine its effect.
The rule that in the absence of outside forces the total momentum of objects that interact does not change?
law of conservation of momentum
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)
What two characteristics of and object determine the objects momentum?
A change in momentum exists whenever a force acts on an object, and the magnitude of the change is dependent on the mass of the object on which the force acts.

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.

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.
Which one of the following quantities corresponds to the rate of change of momentum?
Force. The way Newton specified his law originally, force is equal to the derivative of momentum with respect to time (dp/dt) - that is, to its rate of change.
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.
