Answer:
Physical evidence usually involves objects found at the scene of a crime. Physical evidence may consist of all sorts of prints such as fingerprints, footprints, handprints, tidemarks, DNA material, cut marks, tool marks, etc.
Circumstantial evidence is indirect evidence which creates an inference from which a main fact may be concluded. For example, circumstantial evidence of a murder is not based on first-hand eyewitness accounts, but may consist of threats that were made, fingerprints left at the crime scene, or the presence of the accused in the vicinity of the crime.
