The light

    Can we consider light as a force ?

    can a very heavy light move a 0.00002 gram mass ?

    :confused: a heavy light...? :biggrin:

    If you've ever seen the concept of a laser-driven sailship, then you must realize that light has pressure, and in that sense it can move a mass.

    Light has momentum and momentum flux density,so definitely can act on material bodies with a force...
