Potential energy = - (Work done by conservative force)

Q. Work done by a conservative force is equal to negative change in the potential energy of the system.

Q. Assertion :If work done by conservative forces is positive, kinetic energy will increase. Reason: Here potential energy will decrease.

Q. A body is freely moving under the action of a conservative force. If the work done by this conservative force is 'a', change in kinetic energy 'b' & magnitude of change in potential energy is 'c', then

Q. A body is displaced from position $A$ to position $B$. Kinetic and potential energies of the body at positions $A$ and $B$ are $K_A=70\text{J},U_A=-50\text{J},K_B=-20\text{J}$ and $U_B=30\text{J}$. Then:

Q. Why is change in potential negative of the work done by conservative forces
