while doing homework

Answer 2

According to Physics,

                    When we have applied force on doing something and carried some distance while doing it is know as Work. Displacement should not be zero.

According to me,

                  When we have done any work properly like mesmerizing and thus bi-product of that work can be used to serve others to help others move forward is known as work.
