Question

Define non conservative

Answer 1

Nonconservative forces, such as friction, that depend on other factors, such as velocity, are dissipative, and no potential energy can be defined for them.

Step-by-step explanation:

Answer 2

Non-conservative forces are dissipative forces such as friction or air resistance. These forces take energy away from the system as the system progresses, energy that you can't get back. These forces are path dependent; therefore it matters where the object starts and stops.

Definition: disposed to preserve existing conditions, institutions, etc., or to restore traditional ones, and to limit change.
