## Main Question or Discussion Point

amount of work done by conservative force

=amount of decrement in potential energy

Is this correct?I think yes

Because I have been told that

Work done by non-conservative forces + work done by conservative forces = change in kinetic energy

but

Work done by non-conservative forces = change in potential energy + change in kinetic energy

so it implies

work done by conservative forces= negative of change in potential energy

So that change in potential energy cancels out and Work done by non-conservative forces + work done by conservative forces = change in kinetic energy.
