In respect to this, what is a non conservative force in physics?

Non-conservative forces are dissipativeforces such as friction or air resistance. Theseforces take energy away from the system as the systemprogresses, energy that you can't get back. These forces arepath dependent; therefore it matters where the object starts andstops.

Furthermore, how do you know if a force is conservative? To determine if it is conservative you canfind the actual function u such that F=∇u F = ∇ u . Buta sufficiency test is to take the "cross partial derivatives".Since ∂2u/∂x∂y ∂ 2 u / ∂ x ∂ y doesnot depend on the order in which you take partial derivatives youcan take the partial w.r.t.

Thereof, what is the difference between conservative and nonconservative forces?

In physics, it's important to know the differencebetween conservative and nonconservative forces. The work aconservative force does on an object is path-independent;the actual path taken by the object makes no difference.That's different from the force of friction, whichdissipates kinetic energy as heat.

What are conservative and non conservative forces with example?

Examples: the force of gravity and thespring force are conservative forces. For anon-conservative (or dissipative) force, thework done in going from A to B depends on the path taken.Examples: friction and air resistance.
