Dear Student
Energy conservation- when there is no non conservative force like friction , air drag etc are present.
Momentum- When there is no external force on the system
Angular momentum- when there is no External Torque on the system
All the best.

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
