Question

What is an isolated system?

a) A system with no forces.

b) A system with constant energy.

c) A system with no external forces.

d) A system with constant momentum.

Answer 1

An isolated system is a system in which the net external force is zero. In such a system, the total energy and momentum are conserved.

Step-by-step explanation:

An isolated system is a system in which the net external force is zero (Fnet = 0). This means that no external forces are acting on the system. In an isolated system, the total energy and momentum are conserved. This means that the energy and momentum of the system remain constant over time.
