All Flashcards
What is the difference between individual component behavior and system behavior?
Individual components may behave differently from each other and the system as a whole. System behavior considers the collective interaction.
What is the difference between energy transfer and mass transfer in systems?
Energy transfer involves the exchange of energy with the surroundings (e.g., heat). Mass transfer involves the exchange of matter with the surroundings (e.g., evaporation).
What is the effect of applying an external force at the center of mass of a system?
The system will translate (move as a whole) in the direction of the applied force without rotation.
What is the effect of heating a solid system?
Heating a solid can change its structure.
What is the effect of a system rotating?
The center of mass will move in a straight line or remain stationary, while the system rotates around it.
What is the definition of 'center of mass'?
The average position of all the mass in a system.
Define 'system' in the context of physics.
A collection of objects whose interactions we are studying.
What are 'emergent properties'?
System properties that arise from the interactions of its parts.
What is macroscopic modeling?
Treating a system as a single object when internal details are unimportant.
Define 'lines of symmetry'.
Imaginary lines where if folded along it, the two halves of the object match exactly.
