Which of the following quantities are conserved in an isolated system?
Hints
- A conserved quantity cannot change at all, in either direction.
- One listed quantity is allowed to rise, which disqualifies it.
Show the answer
- A. Angular momentum
- B. Total energy
- D. Linear momentum
Why
Energy, linear momentum, and angular momentum are conserved in isolated systems. Entropy can increase (second law).
