Is an object doing work by falling? by Khuram Rafique

Answer by Khuram Rafique:

Precisely and technically … NOT.

Term ‘work’ should be applied only against resistance force … like moving in air or friction or upward in gravity.

Otherwise there is no meaning in concept of work. According to first law, any moving object should keep on doing work for ever!
