5.3 Open and Closed Systems - Momentum

Enduring Understanding:

Certain quantities are conserved, in the sense that the changes of those quantities in a given system are always equal to the transfer of that quantity to or from the system by all possible interactions with other systems.

Learning Objective:

Define open and closed systems for everyday situations and apply conservation concepts for energy, charge, and linear momentum to those situations. 

Essential Knowledge:

For all systems under all circumstances, energy, charge, linear momentum, and angular momentum are conserved. For an isolated or a closed system, conserved quantities are constant. An open system is one that exchanges any conserved quantity with its surroundings.

SCIENCE PRACTICES 

Argumentation 6.4 The student can make claims and predictions about natural phenomena based on scientific theories and models.

Making Connections 7.2 The student can connect concepts in and across domain(s) to generalize or extrapolate in and/or across enduring understandings and/or big ideas.
