1. The [[work]] it does on a particle is independent of its [[trajectory]].

2. The work done on a particle that moves along a closed trajectory (where the initial and final positions are the same, or d_{i = d_f}) = 0) is zero.

2. The work done on a particle that moves along a closed trajectory (where the initial and final positions are the same, or d_{i = d_f}) = 0) is zero.

When the only forces present in a system are conservative, [[mechanical energy]] is be conserved.
