Conservation of momentum is an example of a law that is never violated.

Enduring Understanding:
A force exerted on an object can change the momentum of the object.
ESSENTIAL KNOWLEDGE:
ESSENTIAL KNOWLEDGE:
The change in momentum of an object is a vector in the direction of the net force exerted on the object.
The change in momentum of an object occurs over a time interval.
a. The force that one object exerts on a second object changes the momentum of the second object (in the absence of other forces on the second object).
b. The change in momentum of that object depends on the impulse, which is the product of the average force and the time interval during which the interaction occurred.
