What is a system in physics?
A collection of objects chosen for analysis, treated as having no internal structure for the analysis.
What is a closed system?
A system that does not exchange matter or energy with its surroundings.
What is an open system?
A system that exchanges matter and/or energy with its surroundings.
What is dynamic equilibrium?
Changes occur, but the system returns to equilibrium.
What are quarks?
The smallest units of matter that make up protons and neutrons.
What are the differences between a closed system and an open system?
Closed System: No exchange of matter or energy. | Open System: Exchanges matter and/or energy.
What is the difference between external and internal forces?
External Forces: Forces acting on the system from outside, affecting overall motion. | Internal Forces: Forces acting within the system, often negligible for overall motion.
