Original law ‘To every action there is always opposed an equal reaction.

Reaction = - Action

Extended/generalized law: Reaction -Q Action, Q is coefficient of proportionality

  4. Report of Director National Physical Laboratory (Council of scientific and Industrial Research, New Delhi). Theme of report: “The shape of bodies is not taken in account by Newton’s Third Law of Motion. Thus originality of thought is not denied. If, proven, yes the opportunity is huge. The investigator may re-submit the project with details of experimentations and list of required instrumentations” (2019).

The theme of comments “‘Finally, your paper has a genuinely physical part investigating possible discrepancies from classical Newtonian physics in its domain of validity” (2018).
  9. Editor Current Science, dated 25 June 2019 on paper dealing with generalized form of third law of motion. “Whereas the first two are definitive and lay the foundation of mechanics, the third law certainly suffers from ambiguities and so the author deserves congratulations for the study of this issue”.
  10. Various scientists suggested the shape based experiments for different bodies in view of Newton’s third law which have not been reported in literature.
