Physical equilibria do not involve changes to the chemical properties of the substances involved. For instance the equilibrium of water vapor with liquid water in a partly filled sealed bottle. It is a physical equilibrium since the water molecules have only changed from liquid to vapor.
Chemical equilibria on the other hand involve changes in the chemical composition of substances. Bond breaking and bond formation is involved. An example would be the dissociation of acetic acid . There is an interchange of of particles between ions and molecules whose rate of exchange becomes equal when equilibrium is established.

How about a marble in the bottom of a tea-cup for a physical equilibrium?
And a saturated solution of sodium chloride (with solid at the bottom) as a (dynamic) chemical equilibrium?

the chemical composition of a system remains same if we check it at any corner of the system . this is chemical equilibrium.
